in reply to how to strip VT100 escape sequences?

How could I strip them from a string knowing that they always start with the ESC character (octal code 033), ends with a letter (upper or lower case), and that an undefined number of digits, commas and space are in the middle ?

Off the top of my head...
s/\033[0-9, ]*[a-zA-Z]//g

NOTE: That won't accutally replace the two examples you gave however, because your examples contain "[" which wasn't in your description.
