Hello.
Can you please extend the documentation entry and explain what 'ucn' actually
means?
'''
There are three levels of warning supported by GCC@. The default is
@option{-Wbidi-chars=unpaired}, which warns about improperly terminated
bidi contexts. @option{-Wbidi-chars=none} turns the warning off.
@option{-Wbidi-chars=any} warns about any use of bidirectional control
characters.
'''
Right now we have 4 levels and 'ucn' is not defined the paragraph.
The following paragraph says
By default, this warning does not warn about UCNs. It is, however, possible
to turn on such checking by using @option{-Wbidi-chars=unpaired,ucn} or
@option{-Wbidi-chars=any,ucn}.
Is that not enough?
Yeah, makes sense. Do I understand it correctly that one can't use
-Wbidi-chars=ucn?
Thanks,
Martin
