I believe the talking newspaper would be a separate spell after the translation spell (the blind person would obviously want it spoken in a language he understood). Yet if a spell can make a newspaper change its language, couldn't there just as well be a spell that makes the reader understand the language already printed?
Whenever I consider the possibility of spells of this type, I see it as a magic that is creating information or knowledge (since we all have to study to learn a new language). One of J.K. Rowling's own Principal Exceptions to Gamp's Law is supposed to be information, yet I see many stories that use plots/spells where this supposed basic wizarding world rule is contradicted. Does anyone else ever consider this, or is it just me?
