And I ported this to PC, linux. This code works correctly here. Looks like its something with lwip/esp32. https://gist.github.com/feelfreelinux/9 ... 44a9ae6186

Ok, updated gist.

Hi Feelfree, You don't seem to have tried fixing the buffer overflow issue that I mentioned on github (receiving the full size of the buffer doesn't leave space for a terminating null byte, so you can't treat it as a string). Are you sure that's not the problem? Angus Forgot to update gist - resize...

Hi! I'm writing IRC bouncer on esp32. Implemented basic functionality, but when I receive data, I'm randomly getting characters replaced like ToggleSwitchWid�Ž�Žû?�gû?�, cherryh.freenode.net @�û?Í352 - Hmm, maybe its something with this buffer to string operation? Thanks! https://gist.github.com/fee...
