in reply to truncate string to byte count

say I have an utf-8 encoded string that I want to truncate to a certain number of bytes.

That's an XY Problem if ever I heard one. What are you really trying to do?

    It is not an XY-Problem.

    It's the actual problem at hand.

    The backgound is a program that implements a (passive) check for a monitoring system where you need to write your message to a pipe but the monitoring system imposes a byte-limit on the message.

      Sounds like it is Nagios. Can‘t you modify the output length of your checks in the database? Regards, Karl
