javalang.tokenizer.tokenize method does not generate the javalang.tokenizer.Character type

[eric3119]

for example when calling the method
javalang.tokenizer.tokenize("'\"'")
the expected result would be of type literal javalang.tokenizer.Character with value '"', but the tokenizer identified it as String with value ''"''.
I don't know if it's a bug or if I'm calling the method the wrong way.
