Default embedded fonts in Reader

Hi everyone,
I read somewhere (but I can't find the link) that Adobe Reader (and by extension Acrobat Pro I presume) will always embed certain fonts in their "core" so that we don't have to embed those common fonts while creating a pdfa.
I'm pretty sure I found a list of those fonts earlier, but again, impossible to find the link ...
1. Is it true or is it my (bad) memory ?
2. If true, where can I find this list ?
Kind regards,
Thomas

Hi again ...
In the following doc, I found :
http://help.adobe.com/en_US/livecycle/8.2/outputForms.pdf
For form designs that are rendered only as PDF forms, use any of the following fonts, which are included
with Adobe Reader to optimize performance:
● Courier Std, Courier Std Bold, Courier Std Bold Oblique, Courier Std Oblique
● Minion® Pro Bold, Minion Pro Bold It, Minion Pro It, Minion Pro Regular
● Myriad® Pro Bold, Myriad Pro Bold It, Myriad Pro It, Myriad Pro Regular
Does this mean I can't avoid embedding those fonts in PDFA, and that the produced pdf will look exactly the same if opened in any version of Adobe Reader ?
Regards,
Thomas

Cannot extract the embedded font - Adobe Reader XI

Hello,
I have an XPS file converted to a PDF with an embedded font inside, when I open the file, as I scroll to a page having '&' in the text (that's my case, but it's probably the same with any special character), a message box shows up saying "Cannot extract the embedded font 'HDGSLM+[my font]'. Some characters may not display or print correctly." and I can't see the special character in the page.
I checked that my font was actually embedded in the PDF (File -> Properties -> Fonts) and seems to be ok, normal characters look fine and the application doesn't say anything until I scroll to the page with '&' inside. Also, other PDF readers show the document fine.
I looked around the forum and saw that other people got the same problem and to them was a bug introduced in Adobe Reader 8.x, but nothing was confirmed by developers.
Can you help me? Is it a bug? If yes, is Adobe working on it?
Thank you.
P.S.
My Adobe Reader version is 11.0.4

Reader can not create PDF files, so you should look for bugs in the software that was used to generate it.

Textfield which accepts multilingual characters with embedded fonts

Hi all,
I have a textfield where I can paste text from different languages with device fonts. Now, I want to input multi-ligual text with embedded fonts.
I have embedded set of fonts, where I can input only english alphabets but not other languages.
Is there a way to input any language characters with embedded fonts?
Thank you.

Thanks for your reply.
I have embedded font as follows,
[Embed(source="myfont.ttf", fontName='myfont', mimeType='application/x-font',embedAsCFF="false")]
With this, I was able to apply this font for english.
I have tried to paste " मैं कौन हूँ? " on a textfield. But I have not shown मैं कौन हूँ? text.
And setting text programmatically did not work at all as
textField.text = "मैं कौन हूँ?";
If I do this with device fonts, every thing work fine but not with embedded fonts.
Is there any thing wrong with my code while embedding font?

Your site was built using tables, whose sizes are defined in your site.
If we look at your first table definition, we can see:
<table width="861" height="1449" border="3" cellpadding="0" cellspacing="0" bordercolor="#868787">
Your table has a width of 861 pixels and an overall height of 1449 pixels. Anything you put into that overall box must fit those dimensions, else
it won't be visible. Anything you add above it will push everything down. You can redefine your sizing to let you edit more inside of the table elements.
This is why, when you type in more text, things act weird. If you are in Dreamweaver, you must find the right cell to put your text into and then enter
text there. Unfortunately, this is going to push things around, which were all lined up using tables. And this gets everything offset with respect to
everything else in your website.
And that is why everyone is saying, "Start Over!"
I just inherited a website that has been put together using tables. I'm going to have to expend considerable effort in rewriting the entire design of the
website because of that. because everything I intend to add to the pages on the site is going to need to be deconstructed in order to get it to work
properly if I'm adding text and pictures that need to line up with each other.
You need something done quick and dirty and the only way I can recommend you do that is to use Dreamweaver to show you the tables you have
and put what you need in a new table that is defined above or below the tables you all ready have defined. Do that and then get back to someone here
who knows how to make a website correctly to clean up your entire website and make it editable -- which will cost you some money, but it will be
money well-spent.
I like to quote this maxim: Good, Fast, Cheap. Pick any two. This works for website design. You can get it fast and cheap, but it won't be good. I
think you may have chosen that route.

Adobe reader cannot extract embedded font after pdf sent via outlook

We have some pdf files that open fine in Adobe Reader 9.1.3. Once we send them via e-mail (we use Outlook 2003), they will not open properly with the error message: "Cannot extract the embedded font 'TWDWSP+TradeGothic-Light. Some characters may not display or print correctly." When we click OK, another error message appears: "An error exists on this page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem." If the files are sent in a ZIP archive, they open correctly, but not if sent individually as PDFs. Can someone help?

It's one of the reasons that it's not recommended to send a PDF via email without Zipping it first. Either the senders or receivers email client may use encoding to make the ransfer faster which can wreck PDF's.
Best bet is to Zip (as you've seen) the file first or post it to a web space and email the link.

Reader does not use or display the embedded fonts

I have an odd problem with both Reader X and XI. Neither one will use the embedded fonts when opened from an email. I can forward from that PC to any other PC and the fonts will display correctly. The HP is Windows 7 64 bit. I can view the document that was forwarded through it on XP, Win7 Win8 or Ipad and it displays correctly. The "use local fonts" is uncheck but it seems to ignor the change.

Issue with adobe reader extracting embedded font

I am unable to open a PDF file using adobe reader (I have Windows 7).
The error message states: cannot extract the embedded font HDJDOS + A Caslon Pro-Regular. Some characters may not display or print correctly.
Any suggestions on how to correct this?

Can you open Reader by itself? If so, try disabling Protected Mode [Edit | Preferences | Security (Enhanced)].

Reader V8 problem with embedded font

Hello,
I'm having problems opening in Reader V8 the PDF file located at http://www.itech.ca/otf-cff.pdf . The file opens correctly in previous versions of acrobat. AR 4 5 6 7. It complains about the embedded font. Can anyone help me identify the reason why the font cannot be extracted ? Is there anything wrong in the PDF file when describing the font, or it's the way I'm generating the embedded font ? Is there any tool I can use to help me debug this ? Any help or hint would be greatly appreciated.
Thanks in advance.

Rabih,
Please repost in the Reader forum. This forum is for pdf specification
issues. Usually, the problems you are having are due to each successive
version of Acrobat adhering to standards more strictly. A pdf with a
problemsome font Acrobat or Reader might have tried to render the pdf
and hope for the best. Now it may reject the pdf.

How to get collection of embeded fonts using plugins in acrobat reader?

I am trying to create a plugin for acrobat reader to display embedded fonts on opened document and will do business logic afterward, but not sure whats the method to get the collection of embedded fonts.
Please give me example of code snippet how to get collection of embedded fonts of opened document.
Thanks

PDDocEnumFonts() will enumerate the fonts in a document for you. You will have to look at each font to determine if it's embedded or not.
Don't forget that to build a plugin for Reader, you need a license from Adobe.

Embedded fonts dissapear (a bit complicated, read on...)

This is the actual case:
There is an SWF which contains just a font to be used by many other SWFs, it is here:
./SharedRessources/ComicFont.swf
Then there is one SWF which imports this font for runtime use:
./Selector/Selector.swf
And another one which also imports this font for runtime use:
./Menu/Menu.swf
They both import the font "for runtime use" and this, relative path: "../SharedRessources/ComicFont.swf".
This works for both Selector.swf and Menu.swf quite well. The font is displayed correctly.
BUT now there is this one:
./Everything/Everything.swf
This one loads Selector.swf and Menu.swf BOTH. The result is: The embedded font dissapears!
The funny thing: If I only load ONE of them, the font is visible.
So: Having 2 SWFs loaded simultaneously which make use of a font which is "shared for runtime use" destroys it for both.
Anyone encountered this problem yet? Any simple workarounds? The not-so-simple workaround would be to do it all directly via Actionscript and letting the Container hold all the ressources. But this would just be very comfortable.
OR could this even be filed as a bug?

After fiddeling around with the code, I actually found a solution:
The Font is embedded as a class, "ComicFont". So using the Loader class the usual way to load more than one module that uses this Font will cause the ComicFont class to be overwritten (and thus lost to the module loaded before)
I ran a test like this for every module loaded:
for each (li:LoaderInfo in loaderInfos) { // for simplicity: Imagine I have all LoaderInfos of all loaded submodules here
trace ("Has class ComicFont? "+li.hasDefinition('ComicFont'));
Doing it the nomal, lazy way, this would output:
Has class ComicFont? false
Has class ComicFont? false
Has class ComicFont? false
Has class ComicFont? true
So it seems just the last module actually contained the ComicFont class. No wonder the font disappeared for all the other modules.
The "trick" was to set the applicationDomain inside the Loader:
var ld:Loader = new Loader();
var context:LoaderContext = new LoaderContext();
context.applicationDomain = ApplicationDomain.currentDomain;
ld.load(new URLRequest(swfName), context);
Now the fonts appear in every module and the output of the loop above is:
Has class ComicFont? true
Has class ComicFont? true
Has class ComicFont? true
Has class ComicFont? true
I hope this could help someone...

Hi gurus!
I have created smartform for pdf invoice via mail to user id. when that invoice send to user id . PDF file is getting a popup -" Adobe Reader - cannot extract the embedded font 'Ariel Bold . Some characters many not display or print correctly ".
I want to remove this unwanted popup. please provide any possible solutions.

Hi ravindra, what i can suggest you is to set a breakpoint just before ur cursor goes into the pdf part and just comment the part when it comes to the popup. its very easy and the best way to do it.

Error: cannot extract the embedded font 'WTNNGO+LiberationMono-Bold' when reading a PDF

I am trying to read a pdf file and I get the error: cannot extract the embedded font 'WTNNGO+LiberationMono-Bold'. Then some of the words are displayed as sets of dots, a dot per character. I have tried Adobe Reader 7 through 11 all with the same error. Apparently some fonts are missing. My OS is 64 bit windows 7.

Tell them to embed the font information into the PDF. You don't have the font on your system so as-is, the PDF needs it to display that font. With embedded font information, you don't need the font.

Error message from Adobe Reader. cannot extract the embedded font 'LICCMC+MyriadPro-Light'. some characters may not display or print correctly. Print looks like gibberish

Trying to view/print PDF documents from website. Print looks like gibberish and is unreadable. Problem is with the embedded fonts. Error message from Adobe says cannot extract the embedded font 'LICCMC+MyriadPro-Light'. some characters may not display or print correctly.

Try Adobe support, that's not a Firefox support issue. <br />

Module not unloading if embedded font was ever used

So, I have a test app that uses modules with the font embeded. Using ModuleManager I am able to load up the module. Once I call   IModuleInfo.factory.create(), I am then able to setStyle("fontFamily", "BPDiet") and the font does show up. The issue I am now having is that once I have used a font from a module, even if my TextArea is no longer using it (I even tried removing the textArea, and replacing it with a new one), the module will not unload.
I read through this "What We Know About Unloading Modules" and I think I am not leaving any references around.They are loaded using the load() defaults. There is no code (that is used) in the module. The modules are not being added to the display, so they never receive focus.
Note that I am unable to run the profiler as suggested in the article as I don't have the premium Flash Builder 4. <grrr>
Note that the first module that is loaded, I can never get to unload, even if I never used the font embedded in it, but all subsequent modules will unload, if I do not use the embedded font. I can live with the first one being pinned as long as I can unload the others that are not in use.
Here is the code from one of my modules:
<?xml version="1.0" encoding="utf-8"?>

A couple things to note; I am calling System.rc() in the unloadCurrentFont() method just to speed up seeing the SWF unload in the debug console. The DoNonImportantWork() is there to just cause some events to happen and to create some objects that will need to be GC'ed. It also let me know that the fonts are not getting registered in Font.
I'm going to have 30 fonts (and more, that designer is busy) that I will need to be able to dynamically load, but right now, loading them with CSS style modules blows up after about 15 because style modules register the font so I cannot unload the CSS swf.

To help eliminate the question of whether the TextArea is being held by something else, I have removed it from the MXML, and now programatically create it. That did not help.
So, I got the trial version of Flash Builder 4 installed on another machine in the office so that I can use the profiler. (The profiler is pretty cool by the way).
After a lot of profiing, I found four paths to the module's FlexModuleFactory.
Two of those paths go to EmbeddedFontRegistry, whose data is static. I could get into it and remove font entry and free up the moduleFactory from there. This is a hack, that entry in/on EmbeddedFontRegistry.font should have been cleaned up by the code removing the fontFamily from the TextArea. (Note that EmbeddedFontRegistry is marked [ExcludeClass], which I assume means I should not really be messing with it.
The other two I cannot get to as they are anonymous. They also don't appear to be referenced, as the Object References shows them both as GC root objects. Here is a screen shot:
I did a search through the sdk code and 'fbs' only shows up as a parameter on the init function of various Marshal support classes, but is not used in the init()
Anyway, these references to the FlexModuleFactory do not get held if I do not use the embeded font in the module.
Here is the updated code:

I really think I've reached the end of what I can do. This really seems like a bug.

Embedded font issues -- Flex not measuring properly

I started this out in one thread ( http://forums.adobe.com/thread/470702 ) and it has progressed into a new, bigger issue. I embedded fonts using the code below. Flex is not measuring them properly or the font I'm using is vertically challenged. I suspect the font I am embedding has different vertical spacing than the default font. I have determined the fonts are embedding by rotating the containers.
Here's an example of what I'm getting:
The right side radio button is the raw display (height works out to 23), the left side radio button I forced the height to 15. Both the radio buttons are set to exactly the same y coordinate. You can see the right hand text is not centered on the radio button. I don't want to go thru the hassle of adjusting every single component height to make the font look centered plus that's an ugly workaround.
I don't think there is anything wrong with my code nor do I think a font swf will help. I sure would like to know what's going on but it is beyond my understanding. Here's my thought. I like the default font the compiler uses when I DON"T embed fonts, looks like this:
I figure if I could embed this font, everything would work properly. I just don't where this font lives. The docs indicate the default font is _serif but it looks more like _sans to me. And I don't know the hierarchy for my platform.
So... Does anyone know either how to fix this measurement issue or where I can find THE True Type font or swf or something that Flex uses as a default so I could embed it?

First off, yes there was a correction to the left hand radio button. I forced the height of the button to be different and that seemed to help center things
After a bit of beating my head against the way, I decided to run a simpler test. I set up a case where I had default fonts side by side with embedded fonts. Since my default.css file had Verdana I decided to use a Verdana embedded font. I figured I could compare them directly and maybe play with advanced anti-aliasing at the same time. I've attached the files (change the txt extension to mxml)
The result was a somewhat of a surprise. I didn't realize that all text really wasn't centered on the component (eg radio button, checkbox) at my default size and below. I do see the small pixel shift, especially in the Button.
So... I have found the "real" font declaration in the defaults.css file, am seeing the small pixel shift with embedded fonts, that using advanced anti-aliasing can help on smaller text, and realized I have to be very careful where I use font sizes smaller than default. I'm guessing that the "perfect" default size on my system would be 12 since that appears what my Verdana.ttf font is based on. My defaults.css file has the font size set at 10. The inability to measure properly is exacerbated when the fonts are embedded.
Now the real question -- anyone have a clever fix?
