UnicodeDecodeError in Str implementation

[emv33]

Checklist

• [X] I am sure the error is coming from Pyrofork's code and not elsewhere
• [X] I have searched in the issue tracker for similar bug reports, including closed ones
• [X] I ran pip3 install -U git+https://github.com/Mayuri-Chan/pyrofork and reproduced the issue using the latest development version

Description

There's a crash in message.text (which, btw, is not str - this is not stated in the documentation, which says message.text is a plain str)...

Steps to reproduce

Add the following message handler to the bot and then write this message anywhere the bot is:

🏳️‍🌈🏳️‍🌈

Code example

@app.on_message(group=-199)
async def test(client: pyrogram.client.Client, message: pyrogram.types.Message) -> None:
    print(message.text[:5])
