A series of emails with Santiago Vila in May to July 2018 strongly
recommended this option: Francisco's translation is unfortunately of very
poor quality, and although Santiago hoped to provide his own, he has not
been able to do so to date. A new or significantly revised translation
can always be added at a later date.
The reStructuredText (ReST) format is still quite readable as raw text,
and is much more capable than the myriad all-slightly-incompatible
variants of Markdown.
Also work around buggy implementations of strfmon() that do not copy
complete multibyte sequences that may be part of a locale's
mon_thousands_sep, thousands_sep, mon_decimal_point or decimal_point.
Current and previous versions of ISO/IEC 9945-1 (POSIX), particularly SUSv3
(2001) and SUSv4 (2008), require strfmon() to return rather meaningless
strings when used with the POSIX "C" locale. In particular, the standard
POSIX locale does not define a currency symbol, a monetary radix symbol
(decimal point) or a negative sign. This means strfmon(..., "%n", -123.45)
is supposed to produce "12345" instead of something like "$-123.45"!
The new xstrfmon() overcomes these limitations by using snprintf() as
appropriate.
This makes the main source code look a little cleaner, at the expense of
background magic happening in the configure-generated config.h. But this
magic was already happening for _GNU_SOURCE, __EXTENSIONS__ and the like.
The only wrinkle is that newer versions of NcursesW cause ./configure to
include "-D_XOPEN_SOURCE=600" as part of the compilation command line--on
systems that support _XOPEN_SOURCE=700. The AC_DEFINE/AC_DEFINE_UNQUOTED
macros automatically comment out any "#undef" lines in config.h, so the
file lib/xopen_source.h works around this limitation. It is
automatically included by config.h.
The Minix C library does not seem to support Unicode well (for example,
wcwidth() returns -1 for UTF-8 byte sequences), the native curses library
is quite buggy, playing around with the Gnulib wcwidth module did not fix
issues with Unicode--it's all in the "too hard" basket!
