Description
When a request is sent that is suppose to return 400 {"error":{"code":"Application_StringExceededLength","message":"The length of the string is X, but it must be less than or equal to N characters. Value: ***}}, WebAPI turns into 500 internal server error if the message contains some characters like emoji.
Assemblies affected
Reproduce steps
Open postman and try to send a patch request for a page with a field with limited number of characters with a value in the request that is longer then this limit and that contains an emoji (i.e. 😔).
Expected result
You are supposed to see 400, Application_StringExceededLength, with the the message "The length of the string is X, but it must be less than or equal to N characters. Value: your original message"
Actual result
500 internal server error
Additional detail
It is not just the emoji issue. Some other special characters are affected as well. No pattern for that seems to be obvious.
