On encoding New Tai Lue

A comparison between the 1994-01 proposal from China and the new SIL beta fonts for New Tai
Lue answers a number of questions I posed in my analysis paper of three 1994 proposals from China(http:www.indigo.ie/egt/standards/iso10646/pdf/tai-analyses.pdf). The following differences between thetwo repertoires are:123456SIL xDB DAI LUE MODIFIER W is missing from the Chinese proposal.
SIL xDC DAI LUE MODIFIER FINAL is missing from the Chinese proposal.
SIL xEA DAI LUE NUMBER ONE ALT is missing from the Chinese proposal.
Chinese x52–x64 are missing from the SIL proposal. Of these, x52–x56 can be generated suing
SIL xDB with a base consonant. x57–x64 cannot.
The names are different. SIL names appear to be more suitable for the UCS; the Chinese names
appear to be Pinyin romanization-based, with an h- prefixed to "high" consonants.
The order of the two repertoires is largely, but not entirely, the same.

Taking the chinese order, the SIL names, and moving the digits to a new column, I have prepared thetables attached. I propose the following disposition of the issues raised in my earlier paper.
1.

Order is a bit peculiar vis à vis Brahmic. Issue still open.
x2B–x35 are vowels, possibly vowel signs? New Tai Lue does not use vowel signs; vowels arespacing characters. Closed.
x36–x3B are possibly final consonants, or consonants with long -AA? They are named MA, NA,etc. just as base consonant have been and they all have a small loop which could be -AA (or -U;
x35 also has the loop). Both Chinese and SIL have coded final consonant glyphs, while still
naming them with the inherent -a. It seems that this appendage is the historical VIRAMA. Do theproposed finals need coding? If one were transliterating my name into New Tai Lue, one might
get the following, where the last is a final -l, codeable with virama but not available in theChinese or SIL glyph repertoires. Issue still open.

More vowels appear at x3C–x42. These appear to be real vowels, but could be V + YA + VIRAMA(cf. xx71, xx72.) Issue still open.
Two unidentified tone marks at x43–x44. Use and names of these still needs to be provided.
Issue still open.
DIGIT TEN at x4F is probably DIGIT ZERO. It is in fact DIGIT ZERO. Issue closed.
Two abbreviation signs at x50–x51. SIL name these and consider them letters. Issue still open.
x52–x56 are base consonant + virama + WA. Issue still open.
x57–x5D are base consonant + virama + LA. Issue still open.

x5E–x60 are base consonant + virama+ NA. Issue still open.
x61–x62 are base consonant + virama+ YA. Issue still open.
x63–x64 are base consonant + virama+ MA. Issue still open.
Are xx62–xx74 required?

For information the Chinese proposed codetable and names are provided here.
In the repertoire given on the following pages, I
have used the order of the Chinese proposal forease of comparison, but as noted above,ordering is still an issue.
