Slightly OT question - except that I'm saving a file from an MFC program :-)

Under XP and Vista, am I allowed any Unicode character in a file name except
the usual few punctuation characters?

I haven't thought about this before, but I have saved one containing a "w
with a ^ on it", and it seems ok. Are there any dangers?

[ The letter w or W with the "to bach" (little roof) occurs in Welsh, but
the letter exists in no known code page, and so you really need Unicode to
get it. I am keen to illustrate the possibilities in the next edition of
my MDI app, and am providing samples with titles like "Dacw Mam Yn Dwad"
(heaven knows whether the 2nd letter of the last word will appear to
everyone here <g>) and a file name "DacwMamYnDwad.mz" seemed like a good
idea!]

I'm also going to do "Sonata in Eb" with a proper flat sign, but that exists
as yet in so few Unicode fonts, that I guess it would be unwise to rely on
it being in the Windows font used by any particular person. :-(

I think that you really can do that!

I have Italian non-ASCII characters in my filenames, like �, �, etc. and I
never had problems since using Windows XP (maybe I had some problems on
Win9x...).

I believe that if your program is built in Unicode mode, you will have no
problem if the file names contain Unicode characters.

Thanks. It does indeed appear to work. However I have been stopped in my
tracks, just before I read your reply. The installer software I'm using
(SetupBuilder - which is otherwise absolutely excellent) was very unhappy
about the idea of compressing a file with a w^ in the name :-( I'll
mention it to the author.

David,

Unicode-only characters in filenames? It's of course perfectly legal but
it's giving a stick to be beaten unfortunately.

Even though your app will most likely be very happy about it, you may
encounter problems with 3rd party tools. Yikes, you just did! Another
example that comes to mind is Winzip: It can compress files with Unicode
filenames. No wait, the very latest version can do it. But do your users
have it? I don't.

I'm currently working on a project where I used an accented character (�) in
the filename. Works fine until I use some code generation tool who messes up
with codepages when used from the command line. And I'm not speaking here of
a unicode-only character.

My 2-cents,

Serge.

That's why I asked :-)

No I don't. I still write batch files to udse the old PKZIP which I bought
donkey's years ago, (it's probably 16 bit, so that's a good point) or use
Windows's native zipping.

Thanks. I am coming back to my original position - discretion is the better
part of valour :-)
