Context & Vietnamese UTF-8

Context & Vietnamese UTF-8

[VnPenguin]

Hi all,
I'm newbie of ConTeXt. I use VnTeX (vietnamese package for LaTeX of
Han The Thanh) with UTF-8 without any problem on teTeX 2.x (with
pdflatex).

Now I would like to try ConTeXt and if it works I'll convert all my
LaTeX src into ConTeXt later.

Anyone could give me some  links to read for this please.

Thank you in advance

Hi there.

I've worked on a bit of Unicode (output) for ConTeXt recently, and I
noticed that Vietnamese needs a little bit more work. There's already
viscii input and x5 encoding output (apparently) working in ConTeXt.

As I understand it, UTF-8 support will then require an update to
ConTeXt's unic-* files (giving named glyphs for input) and then a slight
update to the enco-x5 file. I guess what's really needed are canonical
internal names (like 'ygrave' or 'ohornhook') for ConTeXt's use.

Don't be afraid: it's not difficult, just a bit tedious. So I should ask,
Mr Penguin, how are you with sed, Perl, or Ruby?

Also, do you have any good references for character tables for the
encoding(s?) that VnTeX uses? I don't have it installed on my machine (yet).

With current vnTeX (vntex.sf.net), we can use viscii, tcvn, vps and
unicode (utf8) for input encoding.

I could use Perl and sed (for simple jobs) without problem :)

You can download vnTeX from http://vntex.sourceforge.net

Cool. If there are users of things other than viscii or utf8 who come to
ConTeXt, then they should be able to be accommodated with a little work.

Okay. This first task is more a bit of human pattern recognition:
Take the appropriate Unicode "page":
  <http://www.unicode.org/charts/PDF/U1E00.pdf>
and fill in the attached unic-030 with the glyph names that go down the
list. I've filled in the a's to set the convention (tone accent goes
last, 'dot' gets called 'dotbelow').
(one step after this, and you can get started with your UTF-8 typesetting
with x5 fonts, I think. Another step beyond, and we all can use it with
Unicode fonts, and the final file to edit is to help viscii users hook
into the global VN support we just created for ConTeXt. :)

Cheers, it looks like OSS is alive and well in VN, contrary to the
impression I got in my recent project dealing with the GDVT.
