You may need an hyphen to "stay put" at the end of a syllable; in French, for instance, you have compound nouns such as "arc-en-ciel", where you'd want "arc-" under a note and "en-" under the next note, and you wouldn't want the hyphen to move to the space between the two notes. You want arc- en- ciel, and not arc - en - ciel. Thanks for ideas.
