Yes, problem is happening only when these characters come at initial position. i.e U+0951 and U+0952 in isolation should render with U+25cc > > "Inherited" means that the character inherits its Script property from > the preceding character(s), so if either of the stress signs is preceded > by a Devanagari character, it should make no difference whether the > stress sign itself is categorized as Devanagari or Inherited. looks good, but hmm its really hard to guess characters script when it will be alone. I think one need to add extra check, when character will be at initial position with property inherited Thanks, Pravin S -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org/ iEYEARECAAYFAkxkkbgACgkQLTnsA10u83ywDACgvU/ytDOUSf8++/UktTZG3d68 n5IAoLQKM/yQ5bam571h/iAOUV3kwjHa =kxy/ -----END PGP SIGNATURE-----
