Understanding how fonts work in ConTeXt - Old Content

- Old: A Beginner's Guide to Using Fonts in Mark IV. The idea is that the page says how to easily use fonts (or rather typescripts) in Mark IV, so that you just take a ready-to-use recipe from there and paste it into your document.
Most of the following material comes from the answers I got on the mailing list and/or the documentation (mfonts.pdf). Since crediting people for each and every answer would be cumbersome, I'd like to thank here all of you that helped me understand ConTeXt (especially Hans, of course).
How to typeset in, say, Palatino
\usetypescriptfile[type-gyr] \usetypescript[palatino][qx] \setupbodyfont[palatino,10pt] \starttext Hello world, I'm Palatino! \stoptext
\usetypescriptfile loads a given file (type-gyr.tex in this case). This file usually contains definitions of typescripts. The core typescript files (such as type-tmf.tex, type-one.tex in pdTeX or type-otf.tex in LuaTeX/XeTeX, ...) are already preloaded, so you would usually need this only to load your own definitions.
\usetypescriptfile[type-gyr] will soon become obsolete (TeX Gyre will be the default).
\usetypescript kind of "selects" (?) the specified typescript from that file. It takes up to three parametres and their rôles are still cryptic to me...
One of the keys for defining typescripts is clever usage of the \definefontsynonym command. It takes 2 or three parameters. Example from mfonts.pdf:
The first case - with two arguments - makes
Serif kind of an "alias" (?) for
Times-Roman. Both names are completely independent of name of the font file. This is clever, since instead of fiddling with font file names one can say
Times-Roman and just don't care where it resides on tbe disk. Or even better: one can say
Serif and don't care whether the final version of the document will use Times, Palatino or Latin Modern.
The second one makes
Times-Roman an "alias" (?) for font stored in the file called
tir (probably with some extension?). The third argument specifies the encoding (it might be qx, for instance, or something else) and possibly another options, like
features=smallcaps (for opentype fonts). Encoding is used by pdfTeX only - XeTeX and LuaTeX both use Unicode (Mojca - thanks for this point!). Other possibilities include
handling, but don't ask me about these;).
