While researching the Requests-HTTP library for the Python module, status_codes.py I discovered four character sequences corresponding to specific HTTP status codes (see below).
\\o/for 200 with line 13 :
200: ('ok', 'okay', 'all_ok', 'all_okay', 'all_good', '\\o/', '✓'),
\\o-for 301 on line 26 :
301: ('moved_permanently', 'moved', '\\o-'),
-o-for 404 on line 41 :
404: ('not_found', '-o-'),
/o\\for 500 on line 72 :
500: ('internal_server_error', 'server_error', '/o\\', '✗'),
What is the history of these sequences? Where are they used and why?
