Is there a point code for the concept of language, i.e. a symbol, character or emoji, which represents the concept of a natural or artificial language?
There is a “language selection icon” (see languageicon.org), but this represents language selection, not the abstract concept of a language. I have seen some languages using the at-sign (@) for this purpose, but this looks very inapropriate and confusing.
Is there a language-independet symbol for this or only an ideographic symbol?

I tried searching every Unicode table available without success.
