* Notes on UTF-8
*
* Functions working on UTF-8 strings:
*
* - strchr/strstr
* - strrchr
* - substr_count
* - implode/explode/join
*
* Functions nearly working on UTF-8 strings:
*
* - strlen: returns the length in BYTES, if you need the length in CHARACTERS use utf8_strlen
* - trim/ltrim/rtrim: the second parameter 'charlist' won't work for characters not contained in 7-bit ASCII
* - strpos/strrpos: they return the BYTE position, if you need the CHARACTER position use utf8_strpos/utf8_strrpos
* - htmlentities: charset support for UTF-8 only since PHP 4.3.0
* - preg_*: Support compiled into PHP by default nowadays, but could be unavailable, need to use modifier
*
* Functions NOT working on UTF-8 strings:
*
* - str*cmp
* - stristr
* - stripos
* - substr
* - strrev
* - split/spliti
* - ...
