Eclipse, although Java-based, is actually as platform dependent itself 
as the native SVN library that it uses as it relies on JNI bindings for 
its GUI library (SWT), so in that case it doesn't limit the app's 
portability further.
I don't think users generally care about the implementation as long as 
it works for them. For the developer though, compiling native code for 
all possible platforms that Java can run on is tedious and also in some 
cases more or less impossible... (extreme example: how to compile and 
test JNI native code for IBM's System i or System z, when you're a 
standalone developer with access to nothing but a standard PC?)

But, enough with the native vs. VM war. :)

In the project checkout dialog, under "Text file encoding" (default 
settings can be found in Preferences under Project->Default project), I 
selected the following:

Encoding for local text files: UTF-8
Text file encoding in the repository: Unicode (UTF-8)

It still does not change the way filenames are treated ("international" 
characters are still corrupted), so I think it's safe to say that these 
options only concern the encoding of the contents of the text files, and 
not their filenames.

Okay. :) Thanks for addressing this, and for CVSNT generally.
