Dear Behdad, Consider a font with the following FEA rule in it:
pos u1014' 79 u1032 u1037; which adds 79 to the advance of the first glyph in the sequence u1014 u1032 u1037: [u1014=0+609|u1032=0@-89,-42+0|u1037=0@-55,0+0] vs without the 1037: [u1014=0+530|u1032=0@-10,-42+0] But if we compare with a recent uniscribe we get: [u1014=0+609|u1032=1@-10,-42+0|u1037=2@24,0+0] [u1014=0+530|u1032=1@-10,-42+0] and if we change the rule to compensate for the advance in the windows case we get: pos u1014' 79 u1032' <-79 0 0 0> u1037; harfbuzz gives: [u1014=0+609|u1032=0@-168,-42+0|u1037=0@-55,0+0] [u1014=0+530|u1032=0@-10,-42+0] uniscribe gives: [u1014=0+609|u1032=1@-89,-42+0|u1037=2@24,0+0] [u1014=0+530|u1032=1@-10,-42+0] Yours, Martin _______________________________________________ HarfBuzz mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/harfbuzz
