	Hello. I have managed to successfully install Calibre on my RMBP in the normal dmg way. When I try to run the commands 'calibre-debug -g', I get the output: `ValueError: unknown locale: UTF-8` https://pastebin.com/przZsvdg If anyone can help point me in the right direction so that I can continue to figure out how to be involved in Calibre development. thanks.  |

			It looks like one of your locale related environment variables is set incorrectly. Try running it with 
		
	
		
		
		
		
		
		
		
		
		
		
	
	LANG=en_US.UTF-8 calibre-debug -g  |

			Probably you also need to set LC_ALL, see for example https://stackoverflow.com/questions/...o-utf8-how-fix

 ```bash export LC_ALL=en_US.UTF-8 export LANG=en_US.UTF-8 ``` It worked well. thanks, really. And I can't figure out how this things get work, In the same OS, I can run calibre without add anything to my config, How?
