Meta character . in characterClass is allowed?

[Fazerty]

Hello,

Adding the meta specialCharacter '.' in a CharacterClass shouldn't lead to an error?

Generate a regexp from

{"body":
    {"type":"CharacterClass",
     "expressions": [{"type":"Char","value":".","kind":"meta"}]},
  "flags":"gm","type":"RegExp"}

has this result /[.]/gm

Best regards
