fonts.enc.reencodings works with latex but not with context

[Ulrike Fischer]

I have now reencoded my first chess font. 

I'm now trying to find out how to setup things so that context users
could also benefit from the reencoding. But the equivalent code of
the code working with latex doesn't work in context

\startluacode
   fonts.enc.reencodings["cfss-lsf-std"] = {
         --%bishop
         [66] = 8226,
         --%king
         [75] = 162,
         --% Knight
         [78] = 167,
         --%Queen
         [81] = 163,
         --%Rook
         [82] = 182,
         --%Pawn
         [112]= 223,
   }
\stopluacode

\font\alfonsouc="name:ChessAlfonso-X:mode=base:reencode=cfss-lsf-std"

\starttext
\alfonsouc \char75\char81\char82\char66\char78\char112
\stoptext

I get the error "! LuaTeX error <main ctx instance>:15: attempt to
index field 'reencodings' (a nil value)"

It only works if I copy the code from font-dum.lua to the document.
Isn't the code already loaded?

Btw: There is a small typo in luat-dum.lua. Line 77 is missing an
"s"

        found = kpse.find_file(name,"other text files")
                                                    ^^^ missing.

this feature is indeed not part of context

Dormant code ;-). 

Well in case you want to include it, here a comment:

The pros are: reencode is very easy to use. You only need to find
out the numbers of the original chars. 

The cons are that is difficult to clean up the font. E.g. it seems
impossible to get a font table which doesn't show also all the
original chars (which are in positions not needed after the
reencoding) with the reencode-method. You can't adjust kerns and not
pull characters from other fonts.

A "virtual lua font" (\font\mine=luatex-fonts-demo-vf-1-invf.lua) is
much more powerful (and more fun) and works fine with context too,
so I think I will use it the most time and document "reencode" for
(LaTeX)-users who wants to install a chess font in a simple way.
