BIG PROBLEM: CSS files not loading because of international characters in file name

Question

I have Muse Beta 7 in Spanish.
The program creates a css file called master_a-página-maestra.css in css folder. It is referenced in the resulting HTML code here:
<!-- CSS -->
  <link rel="stylesheet" type="text/css" href="css/site_global.css?3951792836"/>
  <link rel="stylesheet" type="text/css" href="css/master_a-p%c3%a1gina-maestra.css?fileVersionPlaceholder"/>
  <link rel="stylesheet" type="text/css" href="css/index.css?3948175564"/>
When you work locally in your Windows formatted har drive, everything looks fine, but when you upload your files to a server, everything is screwed up. The server doesn't recognizes the URL and returns an error page, resulting in style errors in the entire site.
This can also happens with html files if the title of the page contains international characters or with images if the image file name in your Hard Drive contains international characters.
I already pointed out long time ago Muse was generating file names with international characters like á, ñ, etc but nobody cared about it. Too bad. I had to activate file name customization but I think that Muse should replace automatically this characters in the same way that it replaces other conflictive characters like commas or ampersands.
This is not a fault of the FTP client. Accented characters are not web safe regardless of the FTP client you are using. It is a server side issue. Some servers support it some others don't. I don't mind if it works in Adobe Catalyst server because the final website is going to be in another server and maybe next year when paid hosting is ended the client may move it to another server.
It makes more sense to replace accented characters in file names by their not accented equivalents ('a' instead of 'á', 'N' instead of 'Ñ', etc) and avoid all this problem.

Zak, It is funny you mention it, because the site I am talking about is hosted in 1and1. try this: http://www.artofwalls.com/rosannawalls/biografía.html
As you can see, the offending "í" in the file name causes 1and1 server to throw a "page not found" error. And this has happened with many other servers I have tried since.
Muse boast of generating code fully compatible with all major web browsers but by using international characters in file names it ggenerates code suitable only for very few web servers. International characters have been always a no-no for internet URLs. Internet was designed by people who didn't care about ascii codes beyond 127 so using international characters in html file names is just call for problems.
"to work with your hosting provider to determine how to enable Unicode encoded (UTF-8) file names and HTML files on their servers" is not a viable solution most of the time unless you are a Very Important Client of your host provider. If not, making changes means money for them and if you are the only one who complains, they are going to just tell you to not use international characters in your names.
