The output of "locale charmap" is identical to the result of
nl_langinfo (CODESET) for any given locale. The logic for returning the
codeset was very simplistic. It just returned portion of the locale name
after the period (e.g. en_FR.ISO8859-1 returned "ISO8859-1").
When softlinks were added to locales, this broke. e.g.:
en_US returned ""
en_FR.UTF8 returned "UTF8"
en_FR.UTF-8 returned "UTF-8"
zh_Hant_HK.Big5HKSCS returned "Big5HKSCS"
zh_Hant_TW.Big5 returned "Big5"
es_ES@euro returned ""
In order to fix this properly, the named locale cannot be used to
determine the encoding. This information was almost available in the
rune data. Unfortunately, all the single byte encodings were listed
as "NONE" encoding.
So I adjusted localedef tool to provide more information about the
encoding. For example, instead of "NONE", the LC_CTYPE used by
fr_FR.ISO8859-15 is now encoded as "NONE:ISO8859-15". The locale
handlers now check if the first four characters of the encoding is
"NONE" and if so, treats it as a single-byte encoding.
The nl_langinfo handling of CODESET was adjusting accordingly. Now the
following is returned:
en_US returns "ISO8859-1"
fr_FR.UTF8 returns "UTF-8"
fr_FR.UTF-8 returns "UTF-8"
zh_Hant_HK.Big5HKSCS returns "Big5"
zh_Hant_TW.Big5 returns "Big5"
es_ES@euro returns "ISO8859-15"
as before, "C" and "POSIX" locales return "US-ASCII". This is a big
improvement. The result of nl_langinfo can never be a zero-length
string and it will always exclusively one of the values of the
character maps of /usr/src/tools/tools/locale/etc/final-maps.

all digits are numbers, not all numbers are digits).
Enhance localedef to automatically set the "number" characteristic when
it encounters a digit or xdigit definition. This fixes malfunctionning

By having space automatically classified as "print" type, we can
eliminate the print section from ctype src files completely (they
are just "graph" plus "<space>".

FreeBSD extended ctypes to include numbers (e.g. isnumber()) but never
actually implemented it. The isnumber() function was equivalent to the
isdigit() function in every case.
Now that DragonFly's ctype source files have number definitions, the
number ctype can finally be implemented. It's given a new flag _CTYPE_N.
The isalnum() and iswalnum() functions have been changed to use this
flag rather than the _CTYPE_D digit flag.
While isalnum(), isnumber(), and their wide equivalents now return
different values in locale cases, the ishexnumber() and iswhexnumber()
functions are unchanged. They are still aliases for isxdigit() and
iswxdigit().
Also change ctype.h for isdigit and isxdigit to use sbistype like the
other functions.

The localedef tool can read entire (and unmodified) CLDR posix definition
files, and generate all 6 LC categories: LC_COLLATE, LC_CTYPE, LC_TIME,
LC_NUMERIC, LC_MONETARY and LC_MESSAGES.
This tool has a long history with Solaris. The Nexenta developers
modified it to read CLDR files and created the much richer collation
formats. The libc collation functions have to be modified to read the
new format (called "BSD-1.0") and to handle the new data structures.
The result will be that locale-sensitive tools and functions will now
properly sort multibyte and unicode strings.
