General Recommendation is not to  put special char in attribute name for JSON payload as some implementation may not handle it.

Subject: Representing international strings


OpenID Connect introduced a variable name scheme for international scripts. For example, a name in Katakana script in Japanese will be represented as


where "ja-Kana-JP" part is described in ISO script format.

My question to the list is whether do we want to continue using this scheme even on Swagger. As swagger cannot have # in the variable name, it would become like


etc. This may be OK, but there could be better ways as well, I suppose.

Another obvious ways to deal with it is to use map where the key is going to be the script name and value is the actual value for the parameter.

In any case, I need to find out how to put a variable as the key/name in Swagger definition. Those who knows Swagger well, please help.

Another issue that I have in mind is that what happens if Kanji arrives as "Name" in DDA endpoint. Would the application be OK with it or blows up? Read only case would probably be ok, but if you wanted to send money, for example, and there are Kanji in the Transfer message, what would happen to the US banking system?

Do we need to mandate the current Name like string restricted to ASCII?
