From what I know, no. Note that, for fonts that are not monospaced, it
is not simply a question of how many characters, because glyphs may
have different widths.

You can split your phrase in words, add one word at a time, measure
the width (with get_multiline_type_metrics) and insert a newline
before the word that would overflow. Not very difficult, but as far as
I know there is nothing pre-made in Magick.
