Many agencies specify that all description fields should be filled in in English. This probably hurts my Asian market base a bit with bad translations but works OK-ish.

I'm wondering what to do with names. I'm doing some celebrity editorial shots of Taiwanese actors and politicians. If I enter their English name, the literal computer translation will just be meaningless rubbish. I think I could add notes in description fields on some sites, but would all sites accept that?

Many agencies support only the letters that are used in the English alphabet. Already German, Scandinavian or even Slavic special characters, Asian characters and in generally other characters are not correctly reproduced. This is a major problem in the naming of names and places, for which there is no English equivalent. Some examples - No problem: K�ln = Cologne, but �land, a large island in the Baltic Sea (there exist no English name for the island) - Shutterstock will not accept the geographic name �land - and nobody would search for Oeland or Oland. It's the same situation with names of persons. This is really bad for a specific image search!
