should i make a new pr or could we add to this pr the support unicode emoji in partial emoji converter ?
I also added a check for the unicode emoji since normally all unicode emoji supported by the partial should be inside the list that discord provide.

from discord.partial_emoji import EMOJIS_MAP
class PartialEmojiConverter(Converter[discord.PartialEmoji]):
    """Converts to a :class:`~discord.PartialEmoji`.

    This is done by extracting the animated flag, name, and ID for custom emojis,
    or by using the standard Unicode emojis supported by Discord.

    .. versionchanged:: 1.5
         Raise :exc:`.PartialEmojiConversionFailure` instead of generic :exc:`.BadArgument`
    """

    async def convert(self, ctx: Context, argument: str) -> discord.PartialEmoji:
        match = re.match(r"<(a?):(\w{1,32}):([0-9]{15,20})>$", argument)

        if match:
            emoji_animated = bool(match.group(1))
            emoji_name = match.group(2)
            emoji_id = int(match.group(3))

            return discord.PartialEmoji.with_state(
                ctx.bot._connection,
                animated=emoji_animated,
                name=emoji_name,
                id=emoji_id,
            )

        if argument in EMOJIS_MAP.values():
            return discord.PartialEmoji.with_state(
                ctx.bot._connection,
                animated=False,
                name=argument,
                id=None,
            )

        raise PartialEmojiConversionFailure(argument)

for the moment, only custom emoji are supported.
this should also fix #1582 for the partial emoji part

[Paillat-dev]

so its rely on this pr (for the emoji custom map, so to be able to pr it i will first need this to be merged.
i cannot really suggest change here so i dont know what im supposed to do

[Lulalaby]

You can just work based on this branch, and PR to this branch

[Lumabots]

oups that's mb, i'm usually not able to pr directly on branch, but it might be different since you are a maintainer

[Lulalaby]
