Could somebody please explain what exactly the TeX command
\uchyph=0 does?Background: I found this command in the UK TeX FAQ and it's supposed to prevent hyphenation of acronyms. But when I use it the hyphenation of seemingly random words will not work properly anymore. The default hyphenation looses some points where the word can be split and manual hyphenation rules (via
\hyphenation{...}) are ignored for these words. Manual hyphenation in the text itself (hy\-phe\-na\-tion) is honoured though.
