Isn't that just how language works? When a name doesn't suit your language's writing system it's natural to adapt it in a way that's more accessible. English simply doesn't have an acute accent.

It's why people in English speaking countries are named Michael (or one of the 50+ alternatives) instead of the original מִיכָאֵל, or why BBC reports on Chinese President Xi Jinping instead of Chinese President 习近平.
