At least my name is very easy, Latin works fine for "kawecki" with the only difference that "c" is not "k", is something similar to "tz" or the same as German "z".
But for my name Ricardo that is Ryszard in Polish things get complicated, you have the "sz" that is similar but different to "sh" and the "y" is not "i". The "y" is a sixth vowel that has no equivalent sound in English, German or Spanish, I don't know how to describe how it sounds. In French exist a similar sound but I don't remember what letters they use for it.

Stupidity also evolves!
