Hi Nick!

here is the proposed text for .2b for localedef, as promised

Localedef changes 

Line references are wrt. ISO/IEC 9945-2:1993.

localedef 
change line 5572 to

localedef [-c] [-f charmap [-g repmap1]] [-i inputfile] [-j repmap2] name

(note: "sourcefile" changed to "inputfile", as this is what is used
in line 5617.)

Add after line 5616:

-g repmap1  specify the pathname of a file containing a mapping of
            character symbols to character identifications in
            ISO/IEC 10646. The format of the repmap1 is specified
            in 2.4.2 (repertoiremap). The mapping of character symbols
            refer to the use of character symbols in the charmap, as
            specified with the -f option. This option shall be
            specified when there is a difference between the character
            symbols used in the charmap and in the locale inputfile.

Add after line 5619:

-j repmap2  specify the pathname of a file containing a mapping of
            character symbols to character identifications in
            ISO/IEC 10646. The format of the repmap2 is specified
            in 2.4.2 (repertoiremap). The mapping of character symbols
            refer to the use of character symbols in the inputfile, as
            specified with the -i option or taken from the standard input.
            This option shall be
            specified when there is a difference between the character
            symbols used in the charmap and in the locale inputfile.

New section: (extract from FCD2 14652 clause 6)
2.4.2 Repertoiremap

Locale and Charmap sources may be specified in a coded
character set independent way, using symbolic character names.
The relation between the symbolic character names and characters
may be specified via a Repertoiremap, which defines the
repertoire of characters defined for a locale, and the
symbolic character names and corresponding abstract character
(by a reference to ISO/IEC 10646).

The repertoire mapping is defined by specifying the symbolic
character name and the ISO/IEC 10646 code position in
hexadecimal form (with a preceding 'U') and optionally the
long ISO/IEC 10646 character name in the following syntax:

  "%s %s %s\n",<symbolic-name>,<10646-short-identifier>,<comments>

The symbolic character name and the ISO/IEC 10646 short
identifier are each surrounded by angle brackets <>, and the
fields shall be separated by one or more spaces or tabs on a
line. If a right angle bracket or an escape character is used
within a symbolic name, it shall be preceded by the escape
character. Characters not in ISO/IEC 10646 may be referenced
by the symbolic character names <U80000000>..<U8FFFFFFF>.

The escape character can be redefined from the default reverse
solidus (\) with the first line of the Repertoiremap
containing the string "escape_char" followed by one or more
spaces or tabs and then the escape character. 

Several symbolic character names can refer to the same
abstract character, and are then used as synonyms in locales
and charmaps. The set of <U0000>..<UFFFF> and
<U00000000>..<U7FFFFFFF> symbolic names (no lowercase letters)
are predefined and refers to the corresponding code points of
ISO/IEC 10646 with the same short identifier.
