I am more concerned about the number of characters the string holds.
Say, I want to get the last character:

$str = '€';
echo $str[2];

I suppose most *higher level languages* define the length of a string as
the number of characters the string holds. Cf. ECMAScript's length
property and TCL's [string length]. Even PHP's mb_strlen() returns the
number of characters.

C is quite a different thing.
