Framemaker link to Robohelp 8 generates umlaut in file names - How to remove?

Question

I'm linking translated German Framemaker files into Robohelp.
The heading 1 and heading 2 topics in my Framemaker source files often contain umlauts in the words/phrases.
Unfortunately, when linking to Robohelp 8, the umlauts appear in the topic file names.
And the umlauts are not allowed characters in file names.
How do I remove the umlauts and yet keep a single source construction to my Framemaker-Robohelp project?
(To remove them for the source files would of course be tedious and render the words incorrect.)
(To somehow strip them from the file names would create numerous broken links.)
Our manuals are translated into several languages. I really need the single source aspect of Frame to Robohelp 8 to work properly.
Any process/procedure would be very appreciated!

Answer 1

By default RoboHelp creates topic names based upon the paragraph(heading 1, heading 2 etc.) text on which the FrameMaker document is split. However, this setting can be manipulating the "Topic Name Pattern" option.
To access this setting please follow the following steps.
1. Click File->Project Settings menu to open the "Project Settings" dailog.
2. Go to "Import" tab.
3. Click "Edit" button for FrameMaker conversion settings.
4. Click "Other Settings" on the left tree.
5. On the right you can set the "Topic Name Pattern" settings.
This field allows you to define the pattern based upon which you can generate topic names. One can also insert some specific text to be included in the topic names.
