IMPLEMENTATION: Font setup 94\MT@font@list\MT@font\MT@orig@pickupfonthad to set up the default font, the error font (if it wasn’t the default font), we hadto check for some <strong>package</strong>s that might have been loaded before <strong>microtype</strong> andwere loading fonts, e.g., jurabib, ledmac, pifont (loaded by hyperref), tipa, andprobably many more. Furthermore, we had to include a hack for the IEEEtran classwhich loads all fonts in the class file itself (to fine tune inter-word spacing), andthe memoir class, too. To cut this short: it seemed to get out of hand, and I decidedthat it would be better to use \pickup@font and decide for ourselves whether we’vealready seen that font. I hope the overhead isn’t too large.We use a comma separated list.2664 \let\MT@font@list\@empty2665 \let\MT@font\@emptyAll this is done at the beginning of the document. It doesn’t work for plain, ofcourse, which doesn’t have \pickup@font.2666 2667 2668 \MT@requires@latex2{2669 \MT@addto@setup{%<strong>microtype</strong> also works with CJK in the sense that nothing will break when both<strong>package</strong>s are used at the same time. However, since CJK has its own way of encoding,it is currently not possible to create character-specific settings. That is, the onlyfeature available with CJK fonts is expansion. (Tracking doesn’t really work forother reasons.)
