I think people from places that use idiographic languages that have to be transliterated probably actually have an easier time with English orthography than people whose language uses a Roman script and is pronounced phonetically. People who are used to puzzling through the layer of abstraction/obfuscation that sometimes ambiguous transliterations will have can see that English orthography is almost always substantially different than its pronunciation.
TL;DR: it's easier for a Chinese person to learn to read English aloud than a person from Romania, but the European would have studied it in school either somewhat or a lot
