No, for prefixes,  it just write the prefix handling function, or
print the keymap.  (that's why there's no specific processing for the
various mode variants).  You may improve it and send me a patch ;-)

Read the source!

It says "to 127" right there!

Scanning the while unicode would be even slower.  Well, we could skip
inserting lines form unbound keys, this is where the time is spent
actually.
