# Description Resolves issue #8370 Adds the following flags to commands `from csv` and `from tsv`: - `--flexible`: allow the number of fields in records to be variable - `-c --comment`: a comment character to ignore lines starting with it - `-q --quote`: a quote character to ignore separators in strings, defaults to '\"' - `-e --escape`: an escape character for strings containing the quote character Internally, the `Value` struct has an additional helper function `as_char` which converts it to a single `char` # User-Facing Changes The single quoted string `'\t'` can no longer be used as a parameter for the flag `--separator '\t'` as it is interpreted as a two-character string. One needs to use from now on the flag with a double quoted string like so: `-s "\t"` which correctly interprets the string as a single `char`.
