A nice idea would be to have a t3lib_div::asciiToUpper($string) method
which will only handle 7bit characters but will ignore current locale
(doing tr/a..z/A..Z/ for example). I think there are many extensions
which do a strtoupper for internal purposes without thinking about the
implication with other locales. Even I didn't know about that
restriction in turkish. I thought a-z was "alphabetic" characters in all
languages. :)
