[Code] file_found?(path) and to_ascii+to_unicode.rb

[thomthom]

Right, what you want to do is make your C extension call the Unicode version of the file API's - as converting from Unicode to ASCII in order to try and make Ruby's file functions work will in most cases not work.

Note that the ASCII limitation for SketchUp's Ruby file functions exist only under Windows. Under OSX they should work AFAIK.

Do not ignore Dan Berger's windows-pr package. It goes along with his win32-api package. Has the Windows "unicode.rb"

In windows-apt-0.4.0 there's a complementary file "wide_string.rb"
