Previously, LyX did replace some words with typeset logos, and there was no way to prvent this except putting them, in ERT (bug #4752). Now we have special insets for these words, and standard text is left alone.

I don't think it's worth the effort to implement a more effective
|
|
datastructure, because the number of different fonts in a paragraph
|
|
is limited. (Asger)
|
|
Nevertheless, I decided to store fontlist_ using a sorted vector:
|
|
fontlist_ = { {pos_1,font_1} , {pos_2,font_2} , ... } where
|
|
pos_1 < pos_2 < ..., font_{i-1} != font_i for all i,
|
|
and font_i covers the chars in positions pos_{i-1}+1,...,pos_i
|
|
(font_1 covers the chars 0,...,pos_1) (Dekel)
