Some delimited files generated by machine may be delimited by non-printable charecters such as Ctrl+A , Ctrl+B for either/both fields and rows to avoid complexity in encoding.
CSV import wizard provided a way to specify these characters as delimiters
Steps to Reproduce:
1. Try to open a delimited file with LibreOffice Calc
2. CSV import wizard pops up
3. In separator option un check all but others
4. Try to enter non printable character (tried x01,\u0001 , U+0001)
Wizard cannot take non printable character as seperator
Wizard should provide a mechanism for inputting non-printable characters as separator for both field and row

I would rephrase the idea to allow regular expressions as delimiters. Doing so adds a lot of flexibility while the approach is "well known".
Removing needsUX. Still think a hidden feature of regular expression would be sufficient here.
