I am new to Stack Exchange, so if this question fits better on another board, please let me know.
I am looking for Windows-compatible software that will create a concordance from .pdf and .txt files. Ideally it would work with languages that have diacritical marks (Spanish, French) in addition to English. Is anyone aware of a program that can do this?
I have searched online already and have so far only been able to find old software whose sites no longer work very well.
