Special characters not properly exported to Excel, CSV

First of all, congrats, great plugin!

I see that characters very common in Spanish such as “?” or letters with accents (“á”, “é”, etc.) are transformed to “similar” characters which are compatible with English charset, i.e. “n”, “a”, “e”. Only when exporting to Excel or CSV (not to PDF).

I guess it’s a good will effort, however it may lead to important errors as, e.g. “?” is completely diferent from “n”. For instance, “a?o” means “year”, while “ano” means, literally… “ass”.

Are you planning to use a universal charset compatible with similar languages (French, Portuguese, Catalan…)?

Thanks!
