Github doesn't seem to accept unescaped Unicode characters in JSON. If your JSON encoder doesn't escape unicode characters, you can do this manually using the \uXXXX
syntax of JavaScript string literals.
Rationale: Since it's not defined as a part of the spec, characters are not required to be escaped by JSON.stringify, which is the only JSON encoder/decoder provided as a part of Node.js. Thus, a wrapper function is required to get this functionality.
