$caps() doesn't work properly with certain polish characters: for example title is "I wszystko si? mo?e zdarzy?" it will be converted to: "I wszystko si? mo?E zdarzy?" or "Historia jednej mi?o?ci" --> "Historia jednej mi?o?Ci" "?liwka"-->"?Liwka".
it works fine with other polish characters only after "?", "?".
it appears that the two characters are considered as no letters.

i'm using win2000pro and foobar0.6 beta10

Well, international characters work for me (at least all that I've tried, I can't reproduce your characters, as my browser displays them as question marks). Do $lower and $upper work with these characters?

Btw, I think this should be in the support part of the forum.

the $upper and $lower functions works fine with those characters. the code numbers of my characters are: 152 and 190(i belive ).here is picture : picture

sorry wrong addres: picture

Looks like the text formatting lib needs a little more polish. Sorry. I couldn't resist.
