I have found a tag named unicode-string, which is used to categorize some questions which should properly have tags unicode and strings on StackOverflow.
Most of those questions have at least one of the constituent tags, if not both.
Imho, the hyphenated tag should be replaced by those two tags, unless someone can explain how it conveys any additional information.
This leads to my main question: Is there any way to propose such a multi-tag-synonym, and how would one go about it?
Can and should StackExchange support such synonyms?
If no to both technical but not to the retagging, which way should the synonym go, or should it be retagged manually on a regular basis?
Anyway, I am a bit unsure about how to categorize this properly...
