Putty SSH settings to stop garbled output
Using Ubuntu 18 and tools like glances and iftop would often mangle the output
Changing the default Puttty settings 'Connection > Data > 'Terminal-type string' to 'putty' instead of 'xterm' and setting your PuTTY settings under Translation and ensure that you have UTF-8 set as the character set then save this as the default profile and enjoy :)
