HI Behdad,I also have realized hb_shapes passes hb_buffer_set_script and hb_buffer_set_language default parameters unless the user specifies the opposite.
Does that mean harfbuzz automagically detects the language? Isn't that what the itemizer was supposed to do?

(I attached the thai.txt file)Because your file has a "BOM" (U+FEFF) character at the beginning. With UTF-8, that usage is discouraged as far as I know. At any rate, the space has zero advance and hence is invisible. bEl 27/09/2013 18:41, Behdad Esfahbod escribió:On 13-09-27 12:36 PM, Eduardo Castineyra wrote:This is the json file I got: hb-shape --font-file=leelawad.ttf --text-file=thai.txt --output-format=json --output-file=thaiglyphs.txt --shapers=ot [{"g":"space","cl":0,"dx":0,"dy":0,"ax":0,"ay":0},{"g":"uni0E2B","cl":1,"dx":0,"dy":0,"ax":1207,"ay":0},{"g":"uni0E49","cl":1,"dx":217,"dy":0,"ax":0,"ay":0},{"g":"uni0E31","cl":1,"dx":114,"dy":500,"ax":0,"ay":0},{"g":"space","cl":4,"dx":0,"dy":0,"ax":1122,"ay":0},{"g":"uni0E2B","cl":5,"dx":0,"dy":0,"ax":1207,"ay":0},{"g":"uni0E31","cl":5,"dx":114,"dy":0,"ax":0,"ay":0},{"g":"space","cl":7,"dx":0,"dy":0,"ax":1122,"ay":0},{"g":"uni0E2B","cl":8,"dx":0,"dy":0,"ax":1207,"ay":0},{"g":"uni0E49","cl":8,"dx":217,"dy":0,"ax":0,"ay":0},{"g":"space","cl":10,"dx":0,"dy":0,"ax":1122,"ay":0},{"g":"uni0E2B","cl":11,"dx":0,"dy":0,"ax":1207,"ay":0},{"g":"uni0E31","cl":11,"dx":114,"dy":0,"ax":0,"ay":0},{"g":"uni0E49.sm","cl":11,"dx":114,"dy":500,"ax":0,"ay":0}] I see the cluster, the deltas, the advances, but I'm still missing the glyph indices for the font. 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.
