How to include HTML formatting in Telegram Bot API ReplyKeyboardMarkup buttons?

I’m developing a Telegram bot in C# and I’m stuck on formatting the text in keyboard buttons. I want to make some text bold in the button, but it’s not working as expected.

Here’s what I’ve tried:

public static ReplyKeyboardMarkup GetFormattedKeyboard()
{
    var boldButton = new KeyboardButton("<b>Important</b>");

    var keyboard = new ReplyKeyboardMarkup(new[]
    {
        new[] { boldButton }
    });
    keyboard.ResizeKeyboard = true;

    return keyboard;
}

When I use this, the button shows the raw HTML tags instead of applying the formatting. The button text appears as “Important” rather than Important.

Is there a way to make the HTML formatting work in keyboard buttons? Or are there any alternatives to achieve this? Thanks for any help!

I’ve encountered this issue in my projects as well. Unfortunately, Telegram’s API doesn’t support HTML formatting in keyboard buttons. It’s a common limitation we developers face.

A workaround I’ve found effective is using Unicode characters for emphasis. You could try something like ‘𝐈𝐦𝐩𝐨𝐫𝐭𝐚𝐧𝐭’ or ‘𝕀𝕞𝕡𝕠𝕣𝕥𝕒𝕟𝕥’. These stand out visually without relying on HTML tags.

Another approach is to use symbols or brackets to create visual distinction. For instance, ‘[ Important ]’ or ‘* Important *’ can help the text pop.

While not ideal, these methods can enhance the appearance of your buttons within Telegram’s constraints. Just ensure the text remains easily readable for users.

sry mate, but HTML formatting ain’t supported in keyboard buttons. telegram’s just not built that way. u could try using emojis or special characters to make text stand out tho. like “:exclamation:Important​:exclamation:” or “:fire:IMPORTANT​:fire:”. not perfect, but gets the job done

I’ve been down this road before, and unfortunately, Telegram doesn’t support HTML formatting in keyboard buttons. It’s a limitation we all have to work around.

What I’ve found effective is using Unicode characters to create visual emphasis. For instance, you could try ‘𝗜𝗺𝗽𝗼𝗿𝘁𝗮𝗻𝘁’ or ‘【Important】’. These stand out without relying on HTML.

Another trick is to use symbols strategically. Something like ‘:warning: Important :warning:’ can really catch the eye.

Remember, while these aren’t perfect substitutes for true formatting, they can significantly improve the visual impact of your buttons. Just be careful not to overdo it – readability should always be your priority.
