Consider using message entities instead of converting to Telegram-specific Markdown

[monosans]

Instead of converting Markdown to Telegram-specific Markdown, you could remove all Markdown syntax from the original string and send message entities in the Telegram request. This would make the library more robust and simpler, I believe. There will no longer be 400 Bad Requests from Telegram. It will also allow for a more correct maximum message length, since Telegram counts the length after parsing the message entities. Let me know if you need more explanation with examples.

Can you explain further? I'm not sure which function you are suggesting

If you mean Telegram HTML rendering. It is good! But it will take some time.
The most important thing is to figure out mistletoe support.

Have you ever encountered a 400 error when using the Markdown V2 format?

If so, we should probably maintain an additional HTML semantics

No. Try this:

import asyncio

from aiogram import Bot
from aiogram.types import MessageEntity

TOKEN = ""
CHAT_ID = 0

async def main() -> None:
    async with Bot(TOKEN) as bot:
        await bot.send_message(
            CHAT_ID,
            "This text is bold\nThis text is strikethrough",
            entities=[
                MessageEntity(type="bold", offset=0, length=17),
                MessageEntity(type="strikethrough", offset=18, length=26),
            ],
        )


asyncio.run(main())

As you can see, it does all the formatting without any special syntax.

In fact, parse mode is just an abstraction on top of message entities

Have you ever encountered a 400 error when using the Markdown V2 format?

I've had this 1 time with telegramify, but I can't find the logs anymore unfortunately.

[sudoskys]

I am thinking whether this is feasible. It stands to reason that after grammar parsing, many block tokens can be matched with message entities.

I'll investigate further when I have time.

Some libraries do not support MarkdownV2 format. Perhaps this issue must be resolved.

I started working on my own library, which will use pyromark for Markdown parsing and it will use message entities.

Interesting!, maybe you'll solve the puzzle of the century
