'Telegram does not escape some markdown characters

Telegram does not escape some markdown characters, for example:

This works fine

_test\_test_
But this return parse error

*test\*test*

What I do wrong?

Solution 1:^[1]

String escapedMsg = toEscapeMsg
    .replace("_", "\\_")
    .replace("*", "\\*")
    .replace("[", "\\[")
    .replace("`", "\\`");

Do not escape ] character. If [ is escaped, ] is treated like a normal character.

Solution 2:^[2]

Actually both are getting error.

{
  "ok": false,
  "error_code": 400,
  "description": "Bad Request: Can't parse message text: Can't find end of the entity starting at byte offset 11"
}

sounds like Telegram doesn't support escape characters for markdown, so i suggest you to use HTML instead: <b>test*test</b>

Solution 3:^[3]

The only workaround is to use HTML in the parse_mode

https://core.telegram.org/bots/api#html-style

Solution 4:^[4]

You should use '\\' to escape markup tokens *_[`, i.e. send this instead:

*test\\*test*

Solution 5:^[5]

Use MarkdownV2.

{
    "chat_id": telegram_chat_id,
    "parse_mode": "MarkdownV2",
    "text": "*test\*test*"
}

Just escape these characters:

'_', '*', '[', ']', '(', ')', '~', '`', '>', '#', '+', '-', '=', '|', '{', '}', '.', '!'

and telegram will handle the rest.

Solution 6:^[6]

Ironically if the prase_mode argument is set to markdown instead of using the ParseMode.MARKDOWN_V2 constant in the python without escaping any character send_message function works fine.

Solution 7:^[7]

according to telegram API

In all other places characters '_', '*', '[', ']', '(', ')', '~', '`', '>', '#', '+', '-', '=', '|', '{', '}', '.', '!' must be escaped with the preceding character '\'.

so here is function I've used

text
  .replace(/\_/g, '\\_')
  .replace(/\*/g, '\\*')
  .replace(/\[/g, '\\[')
  .replace(/\]/g, '\\]')
  .replace(/\(/g, '\\(')
  .replace(/\)/g, '\\)')
  .replace(/\~/g, '\\~')
  .replace(/\`/g, '\\`')
  .replace(/\>/g, '\\>')
  .replace(/\#/g, '\\#')
  .replace(/\+/g, '\\+')
  .replace(/\-/g, '\\-')
  .replace(/\=/g, '\\=')
  .replace(/\|/g, '\\|')
  .replace(/\{/g, '\\{')
  .replace(/\}/g, '\\}')
  .replace(/\./g, '\\.')
  .replace(/\!/g, '\\!')

But keep in mind, this means if you mean to use *some text* as bold text this script will render *some text* instead without applying the bold effect

Solution 8:^[8]

pdenti's answer only replaces the first character found in the message. Use regular expressions with the global tag to replace all of them.

String escapedMsg = toEscapeMsg
    .replace(/_/g, "\\_")
    .replace(/\*/g, "\\*")
    .replace(/\[/g, "\\[")
    .replace(/`/g, "\\`");
