Actually even len/length/char_length varies from DB to DB. Of the two I've worked with (SQLite and MySQL), one returns the number of bytes for length where the other returns the number of characters. Neither provide len. MySQL provides char_length in addition to length to return the character count.

True laziness is hard work
