Hello,
I discovered that with one font the \ldots command typesets three colons
(:::).
I found these lines in plain.tex
\mathchardef\ldotp="613A % ldot as a punctuation mark
\def\ldots{\mathinner{\ldotp\ldotp\ldotp}}
saying the \ldots uses character on position 3A. In the font (type 1),
there is really the semicolon on this position.
How to make context to use proper character (\period), which is on
position 2E in the font without changing this file? Or is it possible to
use a special glyph for horizontal ellipsis with \ldots command? (It
exists in the font)
best regads
Jan

Are you sure that we are using plain.tex ?
In mkii
\ldots ->\dohandlemathtoken {ldots}
while in mkiv
\ldots ->\Umathchar "0 "0 "2026

No, for mkii you should look at math-*.mkii files. The relevant file in
this case is math-tex.mkii, which defines
\definemathsymbol [ldotp] [punct] [mi] ["3A]

You need to define a new math encoding (see math-ams.mkii or
math-eul.mkii).

\definemathsymbol [ldots] [inner] [mi] ["XX]
where XX is the location of the glyph.

Thanks for the reply,
it helped.
Exploring the math- files I found other questions.
What's the difference between \definemathsymbol and \definemathcharacter?
I expect that [punct] means punctuation character, but what the [inner]
means? Where can I found what [xx] different characters need?

symbol are cs names (\something) that map to a font glyph.
characters are input character (any ascii/unicode value) that map to a
font glyph
command is a cs name (\something) that maps to a TeX command
(\somethingelse)
> I expect that [punct] means punctuation character, but what the [inner]

inner is same as ord math class (see the TeX book). ConTeXt uses some
symbol names which map back to mathclasses. See math-ini.mkii for a list
(grep for \chardef\math...)
> Where can I found what [xx] different characters need?
In the font :-) You can use (in MkII)
\loadmapfile[name.map]
\starttext
\showfont[full-name-of-font]
\stoptext
BTW, which math font are you using?
Aditya

I played with Serapion from Storm foundry. Math is not complete there, but
some glyphs (as \ldots) are present.
