Bug Type: Strings related
Operating System: Linux
PHP Version: 4.2.2
New Comment:
This is not a bug in PHP; it's down to whether your system
can support this and has the appropriate locales installed.
A quick and dirty example might look this this in C:
#include <ctype.h>
main()
{
char buff[1024];
while(fgets(buff, sizeof(buff), stdin)) {
int i, l;
l = strlen(buff);
for (i = 0; i < l; i++)
buff[i] = toupper(buff[i]);
puts(buff);
}
}
If that little program works, your system supports
this conversion. If it doesn't, then PHP doesn't
either.

Yes, I set LC_ALL/LANG to 'en_US' and try it.

I think your confused by looking on the result of test script with
encoding set to 'ISO-8859-x' instead of 'UTF-8'.
In this case it looks as some characters changed to lower/upper case.
BUT they are not UTF-8 lower/upper case characters:
1) 0xC39C changed to 0xE39C, should be 0xC3BC
2) 0xD0AF changed to 0xF0AF, should be 0xD18F
As result we have not UTF-8 string but a garbage.
If you really like test this issue you should set
'default_charset=utf-8' in php.ini or set encoding to 'UTF-8' in your
browser.

I try en_US.UTF-8, de_DE.UTF-8, ru_RU.UTF-8 - no lack.

So, no way in PHP convert UTF-8 string to lower/upper case?

So you didn't try it..? I only tried your test script and
got the expected result. Whatever the characters are..I've no idea of
them anyway..
btw. AFAIK, setting LANG / LC_ALL to UTF-8 is not correct
way to do it..

According to that HOWTO, it should be something like ru_RU.UTF-8 (and
only if you really have UTF-8 locales)
I'm bogusing this since it really isn't anything PHP can affect..

What you mean "works just fine"?
Did it convert 0xC39C ('Ü' in UTF-8 encoding) into 0xC3BC ('ü' in UTF-8
encoding)? Or 0xD0AF (Russian capital "ya" in UTF-8 encoding) into
0xD18F (Russian lowercase "ya" in UTF-8 encoding)?

I didn't know UTF-8 is a locale..
I tried setting LANG/LC_ALL to that and it indeed
didn't work. When I set those to "en_US" it works just fine.

> Exactly what distribution do you have?
Mandrake 8.1 with following RPMs installed:
locales-2.3.1.2-4mdk
locales-en-2.3.1.2-4mdk
locales-ru-2.3.1.2-4mdk
locales-de-2.3.1.2-4mdk
> How are LANG/LANGUAGE/LC_ALL etc. environment variables

All environment variables set to 'UTF-8'.
> And please, try with the stock php.ini-dist too.
Same result.
BTW, in the php.ini-dist there should be a semi-colon instead of colon
in the line 98:
": is doing." -> "; is doing."
Could you tell me your settings so that I can try them out?
