[TYPO3-linux] t3lib_ts:UnumberToChar(), was: UTF problems on AIX

[Dimitri Tarassenko]

Hello All,

Who is currently working on t3lib_ts (charset conversions)? I am
copying Martin Kutschker on this but maybe someone has any experience
with the problem as well.

This is a forward from TYPO3-Linux - Marius is running AIX on rs/6000,
which is big-endian 64-bit. Apparently, there are some problems in
Unicode number to UTF conversion that is done via byte-shifting, and
UnumberToChar() goes in an undefinite loop.

Anyone seen this before / knows how to fix?

Thanks!

D.

 we run typo3 on an aix server with php compiled as cgi bin interpreter

 if ($title && $title != $upper) $utf8CaseFolding['toTitle'][$utf8_char]

 This function (UnumberToChar) converts UNICODE numbers to UTF-8
multibyte characters. The way it is coded is by bitwise shift.

Since you mention you run AIX, I would suspect there might be a
problem with byte-order while converting to/from Unicode.

Is youre server big-endian or little-endian?

 it's an rs/6000 big endian
 seems that you spotted the problem :)
