Log Message:
-----------
In -Tascii mode, provide approximations even for some Unicode escape
sequences above codepoint 512 by doing a reverse lookup in the
existing mandoc_char(7) character table.
Again, groff isn't smart enough to do this and silently discards such
escape sequences without printing anything.
