For example, this random person:
http://tw.battle.net/d3/zh/profile/弒神殺手-3389/
I tried: http://tw.battle.net/api/d3/profile/弒神殺手-3389/ but without any result.
While for example my own account (without special chars.) seems to work:
http://tw.battle.net/api/d3/profile/DANNEHR-2672/
Edit:It's also not a regional problem cause this EU player gives the same result:
http://eu.battle.net/d3/en/profile/Даррен-2806/
