Good model.
To generate character offsets:
Function StrLenToCharCount

;/
function# $s nBytes

;Converts byte count to character count in string.
;Returns the number of characters that corresponds to nBytes.

;s - string.
;nBytes - can be string length or some offset in string, in bytes.
;;;If -1, this function calls len() to get string length.

;REMARKS
;In Unicode mode, non-ASCII characters consist of more than 1 byte.
;len() and other QM string functions always use byte count.

if(nBytes<0) nBytes=len(s)

ret MultiByteToWideChar(_unicode 0 s nBytes 0 0)
