The big problem with macros for this sort of thing is getting the italics right -- Arabic transliteration typically uses italics in running text. The macro will have to be adjusted (or an italic parameter changed) for every font. See \def\sh@ft on page 356 of the TeXBook. Anyway, the Unicode 1E00--FF block has most of these problematic chars, and LM has incorporated the relevant ones. For other fonts, perhaps Hans could implement a combining command that gives an italics parameter option, though that will differ for regular, bold, etc...

Many thanks, Idris and Mojca. If all goes well, I will move to luatex this summer---that really does seem to be the way to go---and then investigate XeTeX, which I gather is now functioning well with luatex. For now, however, I will have to cobble a macro using hints that Mojca provided. By the way I am using Latin Modern (ec encoding). Very best, Alan

Greetings!

I am trying to typeset some transliterated Arabic and one of the diacritical marks is giving me a problem. How does one put what looks like a breve accent (a cup or concave arc) under an letter in ConTeXT?

I used to use macros for that purpose, with the latest Latin Modern fonts you should have every Arabic transliteration character you need, including the arc under the <h>, ie, ḫ. In luatex you just type ḫ. Try it!

Best wishes, Idris

Hello,

First of all, it's nice if the font provides that character. Which fonts are you using for your document?

I wanted to send you an example of how it can be done in different ways, but there seems to be in interesting problem with XeTeX at the moment, so I wasn't able to play with it.

But in general:

a) simply use character U+032E (combining breve below) It kind-of-works with LM, but not perfect (there has been some discussion about how to improve the behaviour of combining accents in LM)

b) use character brevebelow from LM and use TeX to place the accent, see enco-ini.tex for examples

Of course you can assign your own macro to either of the two options to access the accent more easily.

My hint(s) only work in XeTeX and LuaTeX.

By the way I am using Latin Modern (ec encoding).

With ec encoding you really need to do ugly things. You need to compose a character by more or less manually lowering the breve accent and take care for italic correction yourself. Not even accent primitive can be used for it. And you cannot use the combining accent after the character or the proper Unicode glyph (though the latter might be possible by patching some definition in ConTeXt core), you always need to use a macro. With XeTeX and LuaTeX all that comes (almost) for free. Mojca
