Hi everybody, I am currently in the process of designing a simple OpenType font for Mandaic. As some of you are probably aware, shaping in OpenType as it is recommended by the OpenType standard requires that the application (i.e. the text rendering engine) knows the joining behaviour of the characters.
It seems that there is an error in the joining data for Mandaic as defined by the Unicode standard (table 14-5 and 14-6, chapter 14.12 in version 6.3) and by the file ArabicShaping.txt at http://www.unicode.org/Public/UNIDATA/ArabicShaping.txt. The tables list the character IT as dual-joining and the character IN as right-joining. These two seem to be switched. In the table columns with the actual characters (columns Xn, Xr, Xm, Xl) the correct characters are given (compare the code chart at http://www.unicode.org/charts/PDF/U0840.pdf), but the names (and the relative positions in the tables) are wrong and that error is than taken over into the file ArabicShaping.txt: 0847; MANDAIC IT; D; No_Joining_Group [...] 084F; MANDAIC IN; R; No_Joining_Group The correct characters in the table should be (in this order) * Dual-Joining: ATT, AK, AL, AM, AS, IN, AP, ASZ, AQ, AR, AT * Right-Joining: HALQA, AZ, IT, AKSA, ASH And the correct data in ArabicShaping.txt: 0847; MANDAIC IT; R; No_Joining_Group 084F; MANDAIC IN; D; No_Joining_Group Please advise what I can do to help correct this in some future version of the Unicode standard.
