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.

While there are tools called "localedef" in Solaris and Linux, this tool does not share heritage with any other implementation. It was written independently by Garrett D'Amore while employed at Nexenta Systems, and thus carries the Nexenta Copyright. It was initially released under the CDDL license, but on 4 July 2014, Nexenta reissued the source under the BSD 2-clause license.
