To avoid having to recompile php with the PCRE UTF-8 flag enabled, you can just add the following sequence at the start of your pattern: (*UTF8) e.g. '/(*UTF8)[[:alnum:]]/' will return true for 'é' where '/[[:alnum:]]/' will return false. Also the /u RegEx option provides UTF-8 awareness. The preg_* functions are contentious, because careful use can be safe. If you are unsure what to do, see mb_eregi() as a possible replacement.

This function is flagged because its companion function (ucfirst) is not safe. However, this function is untested.

trim(), rtrim() and ltrim()

May be multi-byte safe if you use UTF-8 only (multi-byte UTF-8 characters contain no byte sequences that resemble white space). Avoid UTF-16 & UTF-32, among others.

It may be multi-byte safe if you use UTF-8 only (multi-byte UTF-8 characters contain no byte sequences that resemble less-than or greater-than symbols). Avoid UTF-16 & UTF-32, among others.
