Hi,

I have a software package, that when it writes files, where the name contains accented or umlaut characters, it converts those characters to multi byte in the filename.

I have written a small Perl script, just to validate that the files exist on disk, based on a list of files contained in a text document The file names in this document have the correct accented or umlaut characters. This script fails on all the files that contain these characters. I think it's because I need to convert these characters to multi byte, to match how they have been named on disk.

However, if I attach the drive to my Windows system then my Perl script works, so I'm assuming that the underlying OS calls on Windows is doing this translation for me.

But, that isn't a complete solution, because Windows is case insensitive, whereas I need my script to be case sensitive.

So, is there any way to force Perl to convert strings, containing these characters, into multi byte, similar to WideCharToMultiByte in Windows C.

Cheers,
Eddie

Perl is Unicode-capable - if you enable it. Read man

perluniintro Perl Unicode introduction
perlunicode Perl Unicode support
perlunifaq Perl Unicode FAQ
perlunitut Perl Unicode tutorial

for details.

Case sensitivity can easily be enabled within Perl where and when you need it - for example within regular expressions.

And Windows uses a different Unicode encoding (UTF-16) than Linux/Unix (UTF-8), bear this in mind.

You'll have to tell Perl which one when to use.
