English does not use accent marks basically. However, some foreign names and nouns (like Dalí, Gaudí, café, fiancé) contain accents symbols.
Then, the question is "is it ok to write without accents marks?".
Example 1. I like Dalí and Gaudí. I talked about them with her fiancé at a café. Example 2. I like Dali and Gaudi. I talked about them with her fiance at a cafe. Example 3. I like Dalí and Gaudi. I talked about them with her fiance at a café.
Is Example 3 natural?
