Description:
------------
In ISO-8859-9 (Turkish) the uppercase letter of "i" is a dotted uppercase "I", the lowercase letter of "I" is a dotless "i". But mb_strtolower() und mb_strtoupper() simply return the ASCII uppercase or lowercase counterparts.

You get the correct result with:
setlocale(LC_ALL, 'tr_TR');
echo strtoupper('i');
echo strtolower('I');

But the wrong results with:
echo mb_strtoupper('i', 'iso-8859-9');
echo mb_strtolower('I', 'iso-8859-9');

It turned out this is because mbstring doesn't take the 
locale into consideration.

I get the same results like jan.

I need to get UTF-8 output for consuming a web service and I configured my php 5.0.4 with --enable-mbstring=all parameter (on linux that has been set with Turkish locale)

I see that mbstring extension has limited language support in source code. (German, English, Japanese, Korean, Russian, Chinese)

Is there a way to add our (Turkish) language to source code? Any references about this extension's source?

[2005-05-13 08:00 UTC] moriyoshi@php.net

Turkish locale would need complete overhaul on the 
entire extension because the locale's character 
properties and required case folding behaviour are very 
special.

PHP-ICU extension could support anything, but that's 
just an ongoing work by l0t3k.

I don't know which is the standard way (0x49 or 0xdd).
In ISO-8859-9 (Turkish),
upper case of 'i' (0x69) always should be translated to 'I' 
with dot (0xdd) ?
If yes, please let me know some URLs which describe 
the mapping.

Any chance this is going to be backported to PHP 5.2? I guess mbstring is going to be obsolete with the Unicode and ICU support in PHP 6.

[2007-01-05 14:33 UTC] jan at horde dot org

Oh, and by the way, this conversion should always happen for iso-8859-9, not only if mbstring.language is set to Turkish, because this is completely useless in real world applications.

[2007-08-17 22:19 UTC] hirokawa@php.net

This change is already back ported to PHP 5.2.
In my understanding, it shouldn't always applied to ISO-8859-9,
because the conversion result is depends on the locale.
(correct ?)

[2007-08-23 16:33 UTC] jan at horde dot org

No. The conversion has to be done this way for iso-8859-9 always, not only if the current locale is Turkish. Turkish is the only language that uses this charset.

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at

Thank you for the report, and for helping us make PHP better.
