Tengwar is a script, I believe; you can write Quenya and Sindarin in it, IIRC. (Also, the language of Mordor - remember the Ring?) Probably there are ways to write a lot of languages using Tengwar.
*nods* A script. In addition to the languages you mention, there are also a couple of “modes” for writing English (used on the title page of LotR, for example, IIRC).
It even has an ISO 15924 script tag “Teng”, so you could mark an entry as being in sjn-Teng (Sindarin, written in Tengwar), or even en-AU-Teng (Australian English, written in Tengwar) (since BCP 47 uses ISO 15924 as one of its sources).
