/** Insertion of accents
|
|
|
|
Proper handling of accented characters.
|
|
This is class is supposed to handle all LaTeX accents, it
|
|
is also possible that the class will change a bit so that
|
|
it also can handle other special characters (e.g. Hstroke)
|
|
Initiated by Ivan Schreter, later modified by Lgb.
