Thanks Behdad,Why is there a space at the beginning of the glyph list? (I attached the thai.txt file)

Do you know what "uni0E49.sm" means?Those are glyph names. Pass --no-glyph-names to get raw glyph number instead.El 26/09/2013 20:23, Khaled Hosny escribió:Use --output-format=json, should be a bit more explanatory. Myself, I often forget which number is which, but you basically get glyph name, cluster value, X and Y advance and delta. The glyph name is equivalent to glyph index, just a bit more readable. The cluster value is basically the index of the corresponding character in the input string (though the relation can be complex). The advances and deltas are what HarfBuzz clients will use to calculate the absolute glyph position, HarfBuzz itself does not do that.

But I don't what those numbers and symbols mean.

This is the output I got from hb-view, is there any documentation to know what can I do with the outcome?If you don't specify an output file name, hb-view will do some sort of Unicode-art to draw the glyphs on the terminal. This works fine on Unicode-capable terminals, but I guess Windows’s cmd.exe is not such a one. You can specify the output file name and format explicitly, see hb-view --help.
