I have a question for people. What are your thoughts on writing accents into characters and using different languages. On one hand, they are an excellent tool to characterize someone, but sometimes I get tired of deciphering a written accent. Or it annoys me when something is written in a language I don't know because I am not picking up all of the meaning within the written text.
I handle this by saying that a character has a given accent or speaks a different language, but I don't ever use it.
What are your opinions on dialogue with languages and accents? How do you write them?
