Oh, and as a code example for walking a utf8 string a character at a time, something like this for the fl_utf8len1() function:

First I'd like to ask you, what is the usecase for "walking through a string character-by-character"?

I ask because in Unicode there are different contexts where the meaning of a "character" is completely different:

• an octet
• a Unicode codepoint
• a grapheme
• a glyphe
• something that is displayed (or considered by the user) "as one undividable symbol"
