Tons of surnames were truncated or spelled phonetically over the years because not everyone wants to hand hold an immigration official through the proper spelling of a name that they can't pronounce and may have characters that aren't in the alphabet they're using. Even if you don't say "screw it, good enough" after the first few syllables you can lose resolution because there can be multiple character combos that generate the same sound in the source language but there may be fewer used for that in the destination language.
