But can it be any more generic than
that in the codeset it specifies, the NUL character corresponds
to a single NUL byte.
that is the question.
I personally never liked gettext(). I just did something with
a dictionary, and used block-injecting C preprocessor macros for
calls, because the ({ static size_t gen_cnt;.. })
right-hand-side extension never made it into a standard, and it
is wasteful to call functions for nothing, especially when the
gen_cnt will be set only once and never change in "real life".
I find that "setlocale() may invalidate the string" painful,
because many functions of the C library do not have _l() variants
that could work with a uselocale() object. Just think about the
scanf() that is used so often, or strtol(): you cannot even
convert a number by standard means.
If i were to design this, i would center on bindtextdomain(),
and just keep it going.
That is of course easier said than done, as only existing
behaviour is streamlined and standardized.
