Description: 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) Actual Results: Wizard cannot take non printable character as seperator Expected Results: Wizard should provide a mechanism for inputting non-printable characters as separator for both field and row Reproducible: Always User Profile Reset: No Additional Info: User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:49.0) Gecko/20100101 Firefox/49.0
I would rephrase the idea to allow regular expressions as delimiters. Doing so adds a lot of flexibility while the approach is "well known". https://help.libreoffice.org/Common/List_of_Regular_Expressions
Removing needsUX. Still think a hidden feature of regular expression would be sufficient here.
