Behdad Esfahbod, as the Harfbuzz designer, was kind enough to answer my questions of how Harfbuzz handles the MVS/NNBSP context. He confirmed my understanding that Harfbuzz follows the Microsoft Universal Shaping Engine in the following ... Thank you Behdad ... >>>>> Given the string <MONG_INITIAL><MONG_MEDIAL>< MONG_LETTER ><NNBSP><MONG_SUFFIX> where MONG is the range U+1820 - U+18AA, Harfbuzz applies the <fina> tag applied to MONG_LETTER The same processing holds for <MONG_INITIAL><MONG_MEDIAL>< MONG_LETTER ><MVS><U+1820 | U+1821> >>>>> It would be nice to find out whether Apple rendering systems follow suit. If anyone knows of an Apple engineer that we could ask, I will follow up on the matter. Or if there are other rendering systems that we should consider, please bring them up. The DS00 charts have been updated. I am also attaching two files that have been helpful to me in considering the range of usage of the MVS / NNBSP. DS04 deals with MVS usage. DS05 deals with NNBSP usage. Comments/corrections/questions are welcome. Let's go on to consider six cases where the MVS/NNBSP affect the shaping behavior of the character immediately preceeding/following the MVS/NNBSP - U+1820, U+1828, U+182C, U+182D, U+1835, and U+1836.
