switching font encodings

switching font encodings

[Mojca Miklavec]

Hello,

I have to print plenty of utf-8-encoded entries from a database. I
will probably output entries as
    \contestant{name}{country}{code},
for example
    \contestant{Đức Đặng}{VNM}{1}

I have defined
    \def\contestant#1#2#3{...#1...}

But what's the easiest way to change the encoding to t5 if the country
code is VNM and to some other encoding if country code is RUS, SER (or
one of other countries using Cyrillic)?
I'll probably use

\usetypescript[antykwa-torunska][ec] % for most of entries
\setupbodyfont[antykwa]

I wanted to use XeTeX, but that I figured out/remembered that XeTeX
doesn't yet support inclusion of images which I need for this
document.

Thanks a lot,
    Mojca

(I need this pretty soon.)

you can try to define multiple typefaces, say mainfont-ec, mainfont-qx, mainfont-t5 and then switch to them using languagespecifics related definitions

The Vietnamese left, I can sleep well again ;)
I swear that they will pay for each single letter that caused us
headaches this year: they'll have to organize the same event by
themselves next year. (But then again: next year both pdfTeX and XeTeX
will hopefully work in a much less painful way.)

But I still can't understand why the following code costed me at least
an hour to trace and find a workaround for it:

\definetypeface [iwona-t5] [ss] [sans] [iwona] [default] [encoding=t5]
\definetypeface [iwona] [ss] [sans] [iwona] [default] [encoding=ec]
\setupbodyfont [iwona,12pt,ss]

\starttext
abc \switchtobodyfont[20pt]\switchtobodyfont[iwona-t5] abc
\stoptext

Here's the output:

The funny part is that it compiles fine on contextgarden (and most
probably compiled OK on my computer as well some time ago: the error
just appeared at once).

There is no defined bodyfont at 20pt, and that is what is causing
the error (indirectly). Add this:

\definebodyfont [20pt] [ss]
   [tf=Sans            sa 1,
    bf=SansBold        sa 1,
    it=SansItalic      sa 1,
    sl=SansSlanted     sa 1,
    bs=SansBoldSlanted sa 1,
    bi=SansBoldSlanted sa 1,
    sc=SansCaps        sa .8,
   tfa=Sans            sa 1.200,
   tfb=Sans            sa 1.440,
   tfc=Sans            sa 1.728,
   tfd=Sans            sa 2.074,
   bfa=SansBold        sa 1.200,
   bfb=SansBold        sa 1.440,
   bfc=SansBold        sa 1.728,
   bfd=SansBold        sa 2.074,
   bsa=SansBoldSlanted sa 1.200,
   bsb=SansBoldSlanted sa 1.440,
   bsc=SansBoldSlanted sa 1.728,
   bsd=SansBoldSlanted sa 2.074]

But why do I have to do it? I would only like that
\switchtobodyfont[20pt] scales the font properly (according to
whatever definitions are default). I can't define that for all the
possible sizes of the font that I want to use in the document.

\switchtobodyfont[iwona-t5,20pt] works OK, but one command after
another doesn't.

strange indeed; anyhow this vector stuff will be dealt ith in pdftex itself soon (the problem is that some font things are global in pdftex and then we can end up in sync problems with resources);

Taco, Mojca,

wouldn't this suffice:

\starttypescript [sans] [default] [size]
\definebodyfont [20pt] [ss] [default]
\stoptypescript

Somewhat shorter...

Best

\definebodyfontenvironment[20pt][default]

\definetypeface [iwona-t5] [ss] [sans] [iwona] [default] [encoding=t5]
\definetypeface [iwona]    [ss] [sans] [iwona] [default] [encoding=ec]

\setupbodyfont [iwona,12pt,ss]

\starttext
abc
\switchtobodyfont[iwona-t5,20pt]
abc
\stoptext

is also ok; some time ago we had auto-bodyfontenv definition but since fonts are often used grouped, it generated many messages (warnings) and was slow too; best to let users be aware of the need to define an environment
