Re: ISO, Unicode; right-left languages

To save time I agree with all of what Richard said except for his final bit :-

1) language (e.g. English, French, Dutch, Arabic, Japanese...)
2) encoding (e.g. ISO 8859-1)
3) direction (normal | reverse) - referring to the file; not the display

First off I don't see anything `normal' about left/right. The ordering is
temporal, not spacial as Richard points out.

What I do not want is to have to cope with two orderings where one is enough.
If there is a need to reorder bytes for the purposes of the display I
would much prefer to do it myself after I have rendered the entities etc
into tokens. Having the user do it as well simply confuses matters.

The one exception I would make is for apperances of out of band entities in
normal text. IE if I have a bit of text "fred ℵℷ" and the entities
are just pushed into standard text I want them to be read left-right since
they are in a LATIN context. To make them read right-left I would have to
put them in a HEBREW context.

This is to make the maths mode work since there may be the odd equation with
hebrew characters (eg HEP equations).

Anyway I have just been digging for fonts and come up with a lot of mf ones.
Does anyone know how to make them into X11 bitmaps in an easy manner. I would
like to have the hieroglyphic font in X11. More importantly I would like the
TeX maths fonts in X11 and ps. i'm not sure about the best way to do this.

Anyone know the ISO enties for hieroglphs? &hierA1; &hierA2; etc?
