Password: rupn4u818n0

However, the password he wrote down turned out to be invalid. Can you help him figure out what his actual password is?

HINT 1:

My friend is Taiwanese.

HINT 2:

HINT 3:

The username and the title contain some relevant information. Make sure you transcribe them properly!

HINT 4:

There are some spaces missing in the "password."

• Considering your first hint, are the numbers suppose to represent letters that sound similar? In Taiwan, the language spoken is somewhat similar to Hokkien, and 4 is pronounced 'si', or 'C', 8 would be 'peh', or 'P', and 1 would be 'yi' or 'E'. I'm not sure about 0 though. – Arch2K Mar 9 at 7:35
• @Arch2K your assumption that Taiwanese language is involved here is right! However, the process is a bit more involved than simply replacing numbers with letters. The final answer should look more recognizable than it is currently now. – PiIsNot3 Mar 9 at 7:43

the latin letters that appear on the keys he hits, except he uses a two-language keyboard such as the one below. Therefore the Taiwanese characters would be $$ㄐㄧㄣㄙ'ㄧㄚㄅㄚㄙㄢ$$ but I don't know what that means, online translators fails at interpreting this. It reads $$chins'iapanan\qquad \text{ (China/Japan?)}$$ which doesn't ring a bell either. Of course each key also features different kanji, but that makes too many possibilities without the help from a reliable translator.
