Collection or Scope creation fails when the name has certain combination of special characters

Creation of scope or collection within a scope with name=Scope_With-Largename_%81 or name=Colle_With-Largename_%81 fails with the below error 

{"errors":{"name":"Length must be in range from 1 to 30"}}.

Name has only 24 characters. Without any special characters I can able to create a scope or collection with 30 characters.

curl -u Administrator:password -i -X POST http://10.112.176.101:8091//pools/default/buckets/default/collections/ -d name=Scope_With-Largename_%81
