Hi! The documentation page of the "strlen" function has a note: *strlen()* returns the number of bytes rather than the number of characters in a string.
Also in the "See also" section there is a reference to "mb_strlen()" which should be used when working with multibyte strings. 2013/6/13 Adam Kazimierczak <kazym...@gmail.com> > Hello Mailing List, > > I found that strlen is often considered as a function that counts > characters in strings, rather than bytes.
