No Problemo :)

Yes, I known all that;  I should have noted that we don't need that
NULLing because in the next line we are affecting it to a sane value. :)

I would also like to be able to create several run&build configurations
for the same project.

But it has to be done. hehe

Humm,  I will risk to say it would work, since all chars on highlight
regexs are ASCII, even if not interpreting the file text as UTF-8.

Ok, so say gnuregex supports UTF8, it will work on current locale
charset, right?  but glib is using UTF-8 :/

Here on FreeBSD, we use gnuregex 0.12 from
http://www.gnu.org/directory/text/regex.html with a few changes
http://www.freebsd.org/cgi/cvsweb.cgi/src/gnu/lib/libregex/regex.c.

By looking at the code I cant say if it supports UTF-8, there is no
mention to it in sources ://



BTW, while looking at this I found a bug on glimmer(?) that might be
related, try this:

1. create a new document
2. write some non ASCII chars, say, للللل
3. search for one of those chars;  You will see that two of them are
highlighted, but if you select the "Case sensitive" check-box it will
work just fine.. weird.

I've looked at the glimmer sources
(libglimmerfile/dialogs/glimmer-dialog-find.c) and didn't found a reason
for this. :(

This works fine on gedit (GtkTextView)..  maybe this is a bug in
GtkSourceView 0.6.0?

Good, the comment is just for making a hard note on that. ;)
