The reason why the UTC should tackle the encoding of Tengwar is not so much because it would help in the publication of Elvish poetry, but because confronting the architectural issues it poses for encoding would make an excellent tutorial case for how the two principles of combining mark order and
logical order impact the task of coming up with an appropriate encoding for a complex script. And it would starkly illustrate the fact that an appropriate character encoding does not necessarily directly reflect the phonological structure of a language as represented by that script.
Some rather old discussion papers on this topic may be found at http://www.evertype.com/standards/iso10646/pdf/tengwar-vowels.pdf and http://www.evertype.com/standards/iso10646/pdf/tengwar.pdf
It *is* a problem.
Thank you, Michael. This is all really interesting. I could get into Tengwar, but real scripts are keeping me busy enough!
There is an interesting parallel between Tengwar tehtar and Hebrew holam, in that both can be positioned above either the preceding or the following base character without any difference in sense. The difference is that in Tengwar the choice depends on the "mode" and so on the language being used, and so is consistent within a text; but in Hebrew the choice depends on both the exact context and on the typographer's preferences. The typographer's preferences should be consistent in a text, or at least in a string with the same character formatting, but the contextual element means that positioning may vary even within a word. In most cases, in Hebrew, the positioning is algorithmically determined, although the precise algorithm depends on the typographer, but there are a few ambiguous cases. A bit of a nightmare. But it does tend to confirm that the UTC need not look at artificial scripts to find issues to stretch its thinking, it can find them in real scripts in common current use.
