Good work. TeXmacs uses the X keysym names, and this is indeed the
correct binding.

The problem you have is that the internal encoding of texmacs is not
ISO-something but instead Cork (a font encoding used by TeX) plus
universal symbols (like "<alpha>", currently only used in maths, but it
looks like that is going to be fixed in 1.0.4).

Cork does not have a codepoint for masculine and ordfeminine. Instead
you should currently use macros called "masculine" or "ordfeminine"
which give the desired layout. This is made harder by the fact that
texmacs currently does not display underlines in a variety of special
contexts (like superscripts and tables).

This macro should be defined in std-symbol.ts along with all other
similar dirty hacks. You have two possibilities:

1. Find a TeX font which provides the desired symbol and see with
Joris what is the correct way to use it.

2. Design a hackish solution with a superscript and table, like this
one (paste in texmacs with Edit->Paste as->Scheme):

(assign "ordfeminine" (macro
(rsup (tabular (tformat
(cwith "1" "-1" "1" "-1" "cell-lsep" "0")
(cwith "1" "-1" "1" "-1" "cell-rsep" "0")
(cwith "1" "-1" "1" "-1" "cell-tsep" "0")
(cwith "1" "-1" "1" "-1" "cell-vcorrect" "n")
(cwith "1" "1" "1" "-1" "cell-bborder" "1ln")
(cwith "1" "1" "1" "-1" "cell-bsep" "2ln")
(twith "table-valign" "T")
(table (row (cell "a"))))))))

Once you have defined these macros (probably in std-symbol.ts, along with
all other related dirty hacks), you could insert them with those
bindings (in text.scm):

("masculine" (make 'masculine))
("ordfeminine" (make 'ord-feminine))

That was not a long post, just a complete and accurate description of
your problem and of your tentative solution.
