Are there any avisynth filter can render subtitle with Emoji?

Emoji is very popular today, Huge number of people use it, and there're also a lot of emoji libraries :
https://github.com/twitter/twemoji
http://emojione.com/

so, my question is:

Are there any avisynth/VapourSynth filter can render SubStationAlpha file with Emoji in it?

I am not a c-language programmer, I don't know how to develop this function, so I came here for help.

I hope in the future, someone can develop an emoji filter with these features:
1. works like vsfilter / xy-vsfilter / vsfiltermod
2. render SubStationAlpha with colorful emoji in it
3. allow user to switch emoji library (eg. twemoji / google emoji / apple emoji ...)

I have tried vsfilter, xy-vsfilter, vsfiltermod.
It seems they do not support emoji yet, because emoji is a new thing for those period.

I tried using "Segoe UI Emoji" (included with Win 8.1) which has color emoji, but the subtitles are monocolor. The problem is the ASS subtitle format defines fill, outline & shadow colors, so a non-standard renderer would be required to show color emoji.

IMHO, the actual problem is, ALL the current implementations of "built-in" color characters in fonts are hacks && non-standard...

Also, and for a change, M$ products don't follow their own specifications

You mean "add support for «fonts with color glyphs»", alright
Because if you don't have a desperate need for "native" color emojis,
then the current versions of (xy-)vsfilter should do fine

Cheers 😇

P.S.: besides, never ever apply italics onto emojis...
not even because of someone's birthday...

Supposedly ASS supports [Picture] events, but I couldn't get them to work. I don't think there is renderer support for them.

If someone was motivated enough, they might try converting emoji to SVG somehow (eg, Inkscape) and using SVG2SSA to make ASSDraw vector art.

EDIT original emoji as SVG here: https://github.com/rodrigopolo/minEm...ji-SVG/img/svg
