I am researching about names in Poland, for example. Here is a name that is *pronounced* (by English speakers) as BIALOWANS .
But in Polish, the L is pronounced as a W, the W as a V, and AN is really one, Polish letter.
The net result is that in Polish the *spelling* is BIAŁOWĄS (two diacritics). The Polish *pronunciation* is BIAWLOVANS .
How does one search for all these different options? I am sure that other languages have their own quirks, too.
