At the limit the key that did not fit was handed back to the client as
plain ASCII, so a long Japanese reading ended in a Latin letter, and a
pending romaji consonant was flushed as ASCII with it (…あka for か).
Commit the completed kana, keep the pending syllable, and transliterate
the key as usual; other languages commit and go on the same way.
