This is a variation of mb_convert_case that works only for UTF-8 strings and that will not convert
to lowercase anything.
This avoids turning "AAA aaa" into "Aaa Aaa"; it maps "AAA aaa" into
""AAA Aaa" instead.
<?php
function mb_convert_case_utf8_variation($s) {
$arr = preg_split("//u", $s, -1, PREG_SPLIT_NO_EMPTY);
$result = "";
$mode = false;
foreach ($arr as $char) {
$res = preg_match(
'/\\p{Mn}|\\p{Me}|\\p{Cf}|\\p{Lm}|\\p{Sk}|\\p{Lu}|\\p{Ll}|'.
'\\p{Lt}|\\p{Sk}|\\p{Cs}/u', $char) == 1;
if ($mode) {
if (!$res)
$mode = false;
}
elseif ($res) {
$mode = true;
$char = mb_convert_case($char, MB_CASE_TITLE, "UTF-8");
}
$result .= $char;
}
return $result;
}
?>
