Bug: can't find end of the entity

Hi,

I just stumbled upon this possible bug (imho):

Traceback (most recent call last):
  File "/usr/local/bin/telegram-send", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.8/site-packages/telegram_send.py", line 107, in main

    result = self._request_wrapper(
  File "/usr/local/lib/python3.8/site-packages/telegram/utils/request.py", line 279, in _request_wrapper
    raise BadRequest(message)
telegram.error.BadRequest: Can't parse entities: can't find end of the entity starting at byte offset 82

While markdown works fine ( echo "birthday Fred" | telegram-send ), the script throws the above exception when finding an uneven amount of markdown characters ( echo "birthday Fred [*1980]" | telegram-send ).

In a manual environment, one can circumvent this by quoting the asterisk ( echo "birthday Fred [\*1980]" | telegram-send ), but there are use cases where this is impossible.

For example, I'm fetching calendar entries per ical from a Google Calendar, and there are entries like "birthday Fred (*1980)" for example. The fetching script can't determine which one of the asterisks is to be quoted. But since the calendar entries are mostly generated, I can't add quotes there either.

So, is there any solution other than "Don't use asterisks in your input data"?
