Calling PHP5-only iconv functions in PHP4
A change in t3lib_cs that made it into RC2 (cvs diff -r 1.53 -r 1.54 t3lib/class.t3lib_cs.php) added some functions that are only available on PHP5 if the user chooses "iconv" (iconv_substr, iconv_strlen, iconv_strpos, iconv_strrpos). If using PHP4 with iconv support, I will get lots of errors:
Fatal error: Call to undefined function: iconv_strlen() in ....t3lib/class.t3lib_cs.php on line 1388
Attached patch checks if the functions are available before calling them.

Oh, no I haven't read that. In fact, I haven't even touched that configuration, because I upgraded from 3.8.x and it has always been like that ("iconv" for t3lib_cs_convMethod and t3lib_cs_utils). This wasn't documented like that on 3.8.x.
So I think the bug here consists of the fact that this setting is not backwards compatible. This has to be documented somewhere or a warning appear in the update wizard, if this is not already the case.
