This is to accompany document ISO/IEC JTC1/SC2/WG2 N2549 (L2/03-098) Proposal to encode the Saurashtra script in the UCS by Michael Everson and Jeyakumar Chinnakkonda Krishnamoorty.
The Saurashtra characters have properties similar to Devanagari and the other Indic scripts. These properties for UnicodeData.txt are covered in L2/03-225.
Linebreaking Property Values
The table below shows the values for the Linebreaking property, as they would be defined in the LineBreak.txt file of the UCD.

L2/03-098 were to be encoded, it would have linebreaking property as shown below:
1X0050;AL # unidentified Saurashtra letterOther Property Values (Proplist.txt)
The Script property value for all of the characters in the proposal (1x0000 through 1x004F)
should be "Saurashtra", and that script value should be added to UAX #24.
1x0000..1x0001 should have the Other_Alphabetic property (Proplist.txt), like
U+0903.
1x0044 should have the Diacritic property (Proplist.txt), like U+094D.
No punctuation characters are specified in the proposal.
Derived Property Values
1x0002..1x0033 are all Alphabetic (Letter Other, Lo), and should end up with the
derived property of Grapheme_Base.
1x0035..1x0044 are all CM and should end up with the derived property Grapheme_Extend.
There are 10 decimal digits 1x0046..1x004F, which should be checked to make
sure they end up with the right numeric and/or math properties.
