The following examples doesn't work as expected: \definefontfeature[emojis][default,color:svg][script=latn,language=dflt] \definefont[gilbert][file:Gilbert-ColorBoldPreview5*emojis @ 13bp] \starttext {\gilbert abcdefghijklmnpqrstuvwxyz} \stoptext Letters are displayed correctly, but ascenders and descenders don't. It looks like characters are inserted like images rather than actual characters. Am I missing something? Thank you in advance. Jairo :)

Thank you in advance. svg fonts are a bit of a mess adn there are not many (scaling, offset etc. and specs kind of fuzzy .. one needs for instance treat the visible area in a special way .. there is no metadata wrt the glyph involved so we need to experiment a bit (i don't want to end up with heuristics

you can try this:
\definefontfeature[color:svg] [ccmp=yes,dist=yes,svg=fixdepth]
and patch lpdf-emb with
-- local y = - b[4] - b[2] - (d.depth or 0) local y = - (d.depth or 0)
and try some more (like emoji) ... no time now ... so you do the checking and later i will look at the result
