Possibly a minor bug report, definitely a feature request. Apologies if this topic has been discussed before.
To make a long story short. I've discovered that when using the Export URIs window (which, BTW, is not accessible in a consistent manner throughout the Shareaza GUI), if you click Copy and then paste the URIs into a text editor, any non-ASCII characters in the "[FileBase]" token are preserved. However when clicking Save and then opening the file in an editor, non-ASCII characters in the "[FileBase]" token are not preserved.
I would imagine that this is not expected behavior for Shareaza. But if it is, I personally prefer it weren't. Even though I can decode the "[NameURI]" token (which I'll now be adding to my format) to get the base file name or just use the clipboard. It would be nice if I didn't have to.
FYI, I'm using Shareaza 2.5.5.0 under Windows XP SP3.
