* 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
|
