Lots of languages have them but their wikipedias don't have that article: French, Swedish, Arabic, Dutch, Turkish, Czech, Latin, Italian, Spanish. Surprisingly even languages with orthographic depth of 1 have them

To be a little more exact: Have large amounts of heteronyms to have them be common and not strange exceptions.

English spelling is horrible, but I feel that the number of English heteronyms is not notably high, especially considering the state of the spelling system.

I think heteronyms are bound to arise in most languages with Latin-based orthography, because they tend to borrow words from other Latin-alphabet-based languages without changing spelling. Some words are bound to collide with an existing word with the same spelling.

seeing as most Semitic languages are written without vowels, I would assume that almost all of them have heteronyms
