_mb_strlen() │ WP 4.2.0

Internal compat function to mimic mb_strlen().

Only supports UTF-8 and non-shifting single-byte encodings. For all other encodings expect the counts to be wrong. When the given encoding (or the blog_charset if none is provided) isn’t UTF-8 then the function returns the byte-count of the provided string.

Хуков нет.

Возвращает

int. Count of code points if UTF-8, byte length otherwise.
