3 # This script attempts to work around some of the more bizarre and
4 # quirky behaviours of htlatex.
5 #
6 # - We've persuaded htlatex to produce UTF-8, which unfortunately
7 # causes it to use huge character sequences to represent even the
8 # safe 7-bit ASCII subset of UTF-8. We fix that up.
9 #
10 # - BUT we have to treat angle brackets (for example, redirections in
11 # shell script snippets) specially, otherwise they'll break the
12 # generated HTML. (Reported by Johannes Hoff.)
13 #
14 # - For some reason, htlatex gives a unique ID to each fancyvrb
15 # environment, which makes writing a sane, small CSS stylesheet
16 # impossible. We squish all those IDs down to nothing.
