Are you a fucking Userbot?

Yeah, TDesktop actually strips \uFE0F client-side before firing the request. Telethon is just a raw MTProto wrapper so it doesn't sanitize anything for you. You just have to strip it manually.

It's almost always the exact same character (\uFE0F). It's the universal Unicode variation selector that keyboards automatically add to force the colorful emoji style instead of plain text.
​Just run .replace('\ufe0f', '') on all your emoji strings before passing them to the API. That single replace will fix the errors for the rest of the standard emojis too.

The red heart emoji "❤️" includes a hidden Unicode character (\uFE0F) that Telegram's API rejects. Just strip it out and wrap the reaction in a list using types.ReactionEmoji.

from telethon.tl import types

cleaan = reaction.replace('\ufe0f', '').replace('\uFE0F', '')

await client(functions.messages.SendReactionRequest(
    peer=peer, 
    msg_id=msg_id, 
    big=True, 
    add_to_recent=True,
    reaction=[types.ReactionEmoji(emoticon=cleaan)]
))

Hi and welcome to the group. Before asking any questions, please read the rules from the group's description, and don't forget to read the docs. Make sure you are using the latest version with pip3 install -U telethon, since most problems have already been fixed in newer versions.

Has this been updated and how do we do that in telethon?
For now I just use html rich input type constructor and pass the raw html directly :(

Telethon Chat

31 August 2026 08:45

i haven't had it happen myself, so i don't know if the latter is enough. i would expect so

Telethon Chat

31 August 2026 08:43

I mean it's good for these use cases atleast

Ephemeral messages was needed actually, idk about rich messages tho

Telethon Chat

04 September 2026 16:40

use the *Markdown or *HTML variant depending on your syntax.

Telethon Chat

04 September 2026 16:39

See rich message formatting options and use the raw types available in Telethon.

If you look at data_message_reactions.cpp, it passes the emoji to Ui::Emoji::Find(). TDesktop actually sanitizes and strips that \uFE0F in its UI engine before ever making the API call. Since Telethon is just a raw API wrapper without a UI engine, it doesn't do that for you. You just have to strip it manually.

TDesktop adds this character by default.

perfect thanks I will try to implement

Telethon Chat

03 September 2026 09:56

is there a list of such hidden characters for other emojies or is it the same for all emojies? because likely I have this problem not only with heart emoji, a lot of such errors for other emojies, it's just that I verified only for heart emoji that it's 100% in available list

hello why might I be getting Invalid reaction provided (only emoji are allowed) (caused by SendReactionRequest) for following

await client(functions.messages.SendReactionRequest(
peer=peer, msg_id=msg_id, big=True, add_to_recent=True,
reaction=reaction,
))

There's no hurry tho I'm not doing it anytime soon

Telethon Chat

31 August 2026 08:45

Yeah, and im certain sure as you it can be from that

But myself in years, i haven’t seen the issue after layer update

Telethon Chat

31 August 2026 08:44

tdesktop sometimes makes a commit of a layer that's not finished yet, so that's an option, yes

see diff.telethon.dev. it uses tdesktop. if you toggle the checkbox to view the same layer multiple times, you will see a lot of duplicates

31 August 2026 08:41

For now it's new and probably a bit complex to get along with for now

Ofc they will be used, but usage percentage is what judges the feature need in platform
