You cannot specify an odd (such as \u04FF) character to avoid trying to escape because it validates that it is between unicode 0 and 127 which are all common characters.
Error received:
Failure validating configuration option quote. Expected a character between 0 and 127 but value was actually 191.
How do you disable the behavior of escape or comment or quote? None of these are needed and all 127 characters in the files are common characters in the data.
