[bug #55215] [PATCH] gpinyin.1.man: Unknown characters and failed adjustment

[Bjarni Ingi Gislason]

Follow-up Comment #2, bug #55215 (project groff):

  I use the latin1 locale.

  I adjusted the patch to accommodate ASCII output and compatibility mode.

#

1) Make compatibility and ASCII output (device) mode available.

2) Define a fallback character for an unknown special character, both
for "nroff" and "troff".

3) Adjustment of a string to both margins "always" fails.

  Use (generally) only a left adjustment for the text in question.
