Aliaksandr Kalenik	67fe8d66b2	LibWeb: Skip font if it doesn't contain needed glyph in FontCascadeList ... Before this change, we were only checking for actual glyph containment in a font if unicode ranges were specified. However that is not sufficient for emoji support, where we want to continue searching for a font until one containing emojis is found.	2024-09-06 08:30:30 -04:00

Aliaksandr Kalenik	2cb0039a13	LibGfx+LibWeb: Produce font cascade list in CSS font matching algorithm ... According to the CSS font matching algorithm specification, it is supposed to be executed for each glyph instead of each text run, as is currently done. This change partially implements this by having the font matching algorithm produce a list of fonts against which each glyph will be tested to find its suitable font. Now, it becomes possible to have per-glyph fallback fonts: if the needed glyph is not present in a font, we can check the subsequent fonts in the list.	2023-12-10 17:32:04 +01:00
