This is done in
void TexFilter::process(FilterChar * & str, FilterChar * & stop)

If the sequence "\-" or "\/" is detected (and is not at the beginning
of str), then the two characters are deleted. To compensate for this,
two zero characters (with width 0) are added at the end. Moreover, the
width of the character immediately preceding the sequence is increased
by the length of the sequence so that replacements work correctly.
