[poppler] Graphical caracter filtering

[stefano.rubino]

Hello,


I've tested the poppler library.
I did a piece of code, perhaps I missed something,
but I haven't find the way for desactivating/filtering the graphical caracters.
For instance, for a pdf document containing matrix brackets
I get piece of the graphical brackets as many single character.
Is there a way for filtering them ?
Is there a poppler function, or poppler configuration (tag, flag, ...) or ... ?

Thanks for your help

S.R.
