When displaying Chinese help information, the program does not respond.
The code enters a dead loop in file
"libgetopt++/include/getopt++/DefaultFormatter.h"，
because some Chinese help information does not contain spaces.

It seems that the best approach for Chinese translations would be to:
- add spaces at sentence or word breaks in translations before 35 or 45 bytes,
if that is the length unit, worth of characters are output in each column; or
- add a language dependent line breaking strategy, to honour characters not to
be placed at the beginning or ends of lines or split; or
- split between characters, as with long strings in other languages.
