    1. I send some plantuml formatted data to the bot…

      Maybe a good hint. Try to use “` and “` around the text. Otherwise I got issues that Telegram parses my text eg. Telegram can’t deal with ~~ symbols in Telegram (will cause a strikethrough). Which is a valid format in plantuml. Like: git ~~> deploy (arrow).

      Nevertheless, a nice feature would be to send plantuml to somebody with @umlbot or something in another chat, which then automatically sends the image to the other telegram user.

      1. I have uploaded a picture in the post regarding A ~~> B and A ~> B, how the bot renders it. What did you get? Is it possible for you to share with us some screenshots?
