Re: 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.	[reply]

Sounds like it is Nagios. Can‘t you modify the output length of your checks in the database? Regards, Karl «The Crux of the Biscuit is the Apostrophe» `perl -MCrypt::CBC -E 'say Crypt::CBC->new(-key=>'kgb',-cipher=>"Blowfish")->decrypt_hex($ENV{KARL});'`Help	[reply] [d/l]
