While adjusting my localedata patch script to the latest glibc uploads
I discovered a surprising difference in some categories — for example:
(sid-amd64)tglase@tglase:~ $ LC_ALL=C ./tstspc
U+0009
U+000A
U+000B
U+000C
U+000D
U+0020
(sid-amd64)tglase@tglase:~ $ LC_ALL=C.UTF-8 ./tstspc
U+0009
U+000A
U+000B
U+000C
U+000D
U+0020
U+1680
U+2000
U+2001
U+2002
U+2003
U+2004
U+2005
U+2006
U+2008
U+2009
U+200A
U+2028
U+2029
U+205F
U+3000
The test program is thus: gcc -O2 -Wall -Wextra -Wformat -o tstspc tstspc.c
//--------------------------------cut-here------------------------------

main(void)
{
wint_t wc;
if (!setlocale(LC_ALL, ""))
err(1, "setlocale");
#define DOIT(lim, fmtstr) do { \
while (wc <= lim) { \
if (iswspace(wc)) \
printf(fmtstr, (unsigned int)wc); \
++wc; \
} \
} while (/* CONSTCOND */ 0)
wc = 0;
DOIT(0xFFFF, "U+%04X\n");
DOIT(0x10FFFF, "U-%08X\n");
return (0);
}
//--------------------------------cut-here------------------------------
In my localedata patch script, I take specific care to change the
copy of i18n_ctype before applying it to C.UTF-8 as follows:
space → <U0009>..<U000D>;<U0020>
cntrl → <U0000>..<U001F>;<U007F>
blank → <U0009>;<U0020>
They are as mandated by POSIX for the C locale. I believe I said
in my original 2013 proposal for a C.UTF-8 locale that it should
be as close to C as possible while using UTF-8 as encoding.
For these curious, I’m attaching the current WIP of said script.

# Installs UTF-8 charmap shipped by mirabilos-support generated from
# MirBSD but glibc-compatible into the glibc locale souce directory,
# to update wcwidth data (search for “Character width according to”)
# and the i18n_ctype data taken off glibc git master to enable those
# glyphs added in later UCS versions at all, to (find “It covers”) —
# not always the same version the charmap ships, but close enough at
# least — patching the C.UTF-8 and Turkish localedata appropriately,
# handling i18n for stretch glibc and older as well. This also fixes
# Turkish title-case i→İ and C.UTF-8 supporting UCD 9 only, not just
# making ䷀ fullwidth again (bad width tablegens recently sprouted).
