My understanding is that all of the arcane, language-specific glyph munging rules are handled transparently (or will be). I've fiddled with it a bit with Cyrillic, and one of my students and I experimented with Arabic. The results with Cyrillic were perfect (although just typing Russian has never been problematic in LC, moving text around and looking at chunks of text required lots of hoop-jumping. Arabic and other RTLS still have some problems, but they're light years ahead of what we've had before.

No, I haven't for 2 reasons:

1. Time (and by time I mean that I will have to do a search and replace 
for thousands of numToChar statements).

2. Money (by that I mean that, currently, there is no incentive for me 
to change as my programs
work as they are [version 4.5] and the money I am making from my 
programs currently comes to about $150 per year).

However; "just for fun" (which, in my books at least, is the best reason 
to do this sort of thing<0, if
I can find the time this coming weekend, I will try with my PISMO 
programs, and then, if that works,
at a lter date with my Devawriter.

However; as I understand things the problems associated with languages 
that do not write in a
straightforward RTL or LTR way will not be sorted out; my Devawriter 
will still need all its
sub-routines to arrange letters:

Consider the Sanskrit word "Karma"; I type in k - a - r - m - a and the 
output has to be:

'kamra' (which is read and pronounced 'karma').

Similarly with the word "hindi": I type h - i - n - d - i and the output 
has to do this:

i - h - i - (nd)  where '(nd)' is a "funny letter" (conjunct consonant) 
formed when a 'n' knocks up
against an 'h'.

I have not found the Unicode system in versions of RR/LC from 2 to 6.7  
a source of difficulty;
in fact, far from it, they have been a source of great joy as I have 
been able to successfully
been able to carry my Sanskrit thing "off".

"glyph munging rules" (what a whacked-out phrase; lovely) may be there; 
but certainly not for
Sanskrit unless one uses exactly the half-cocked halant system that 
others use that does not
do the writing system any favours; and certainly not for a writing 
system that has to access thousands of additional characters in the 
Personal Private Use areas of the Unicode system that are specific to
my specialist fonts.


Best, Richmond.
