You would be naïve to think that, especially were you to write that on your résumé. That English has no diacritics is a façade built up to escape the fact that our keyboards make no provision for them.

(A little bit forced, but those are all English words I learned as properly having those appropriate diacritics, when I first learned those words back in grade school.)

Look those words up in the dictionary and they won’t have the diacritics, except as an alternative spelling. They’re loan words, and it’s a stylistic choice.

Ask 95% of laymen to write those words and there will be no diacritics, and the language is defined by its users.

Sure, let's look them up in a dictionary: https://www.merriam-webster.com/dictionary/resume

résumé (noun) variants: or resume

Huh.

Nice of you to skip over the first, primary entry and select the secondary entry. The primary entry has no accent characters.

[jcranmer]

The first entry is for "resume", the verb, which is a different word than "résumé", the noun. Note that none of the definitions provided for the verb "resume" would come close to working where someone intends to use "résumé", the noun.
