System.getProperty with foreign language

Question

Hello All,
I've developed a program that uses System.getProperty("user.home"), in order to transfer files to that location.
Everything's going well as long as I'm using English version.
When one of my customers ran this using a foreign language (Turkish, but it seems to have the same effect on other languages), instead of c:\documents and settings\administrator, he got a wrong fonetic path, i.e. C:\DOCUMENTS AND SETTÝNGS\ADMÝNÝSTRATOR (check the I's, they're not the same), although he has the English path in his computer.
You can see this also when you change the regional settings in an English based Windows to Turkish.
How can I make the System property look at the correct path (again, this happens in other languages as well)?
Thanks,
Barak

Hmmm.... I didn't think I used toUpperCase in my code. When all else fails, my advice is to read the API...
[http://java.sun.com/javase/6/docs/api/java/lang/String.html#toUpperCase()]

Note: This method is locale sensitive, and may produce unexpected results if used for strings that are intended to be interpreted locale independently. Examples are programming language identifiers, protocol keys, and HTML tags. For instance, "title".toUpperCase() in a Turkish locale returns "T?TLE", where '?' is the LATIN CAPITAL LETTER I WITH DOT ABOVE character. To obtain correct results for locale insensitive strings, use toUpperCase(Locale.ENGLISH).
