In fact once you get right into it I think you will find Tibetan is
considerably more complex than Devanagri - at least modern incarnations of
Devanagri. This is one of
the reasons it was eventually found necessary to adopt a very different
model in the Tibetan block than that used for other Indic scripts.

Yes it is poorly documented. There was e.g. no list anywhewre of all the
combinations that occur in Tibetan - I know there are rules about which
characters can combine with each other in proper Tibetan and in Sanskrit
written in Tibetan but all these rules
break down when it comes to e.g. writing Mongolian and Chinese words in
combinations in certain astrological and medical texts and, especially in
forming Tibetan contractions (kung yig).
BTW I know Tibetan quite well - In fact I've been speaking and reading
Tibetan on a daily basis for 29 years now. I've also written a number of
different Tibetan applications and created several Tibetan fonts.

No it is not always used in a standardised way when written in texts - this
is the sort of thing that is poorly documented.

Do look at 3.0 - this now allows you to encode any consonant stacked with
any other consonant (something which occurs in Tibetan though you won't find
it documented in any book on the Tibetan script or language - even native
ones) There are no real "recently created" characters - what you are
thinking of is probably the letters pa (U+0f54) and pha (U=0f55) combined
with tsa 'phru (U+0f39) which are used by Tibetans in India for
translitterating the sounds "va" and "fa" - this is not in fact new
though in Tibetan texts published in the PRC other ways of translitterating
these sounda are used. In old texts and in contractions you will also find
combining with several other consonants.
As far as Tibetan vowels and consonants everything is now covered as is most
punctuation The only "missing" Tibetan characters are some unusual
characters found in some rNying-ma and Bon-po texts, some unusual
punctuation marks and carets, and some astrological symbols used in
almanacs. There is also probably a need for subjoined combining forms of
U+0f88 and U+0f89. However no one should hold off implementing Tibetan until
these characters are added though - you can make a very good implementation
of Tibetan using Unicode v3.0. These missing characters, if and when they
are added, should not effect the basic architecture or coding of any Tibetan
implementation based on v3.0.
BTW if you are really interested in Tibetan or have any questions about the
properties etc. of characters in the Tibetan block you might want to join
the Tibetan list email@example.com mentioned by Sarasvati. I think you can
ask Sarasvati to subscribe you.
