Like |strpart()| but using character index and length instead of byte index and length. When {skipcc} is omitted or zero, composing characters are counted separately. When {skipcc} set to 1, Composing characters are ignored, similar to |slice()|. When a character index is used where a character does not exist it is omitted and counted as one character. For example: strcharpart('abc', -1, 2) results in 'a'. Can also be used as a |method|: GetText()->strcharpart(5)
