According to the manual [1] the format requires that field names match [a-zA-Z%][a-zA-Z0-9_]* but it allows any characters in the value other than an unescaped newline. For example, the command echo "\"country\",population\nÖsterreich,8.58" | csv2rec --strict | rec2csv works as expected. Somewhat worryingly, the format specification does not say anything about \0. I'd rather see use of \0 explicitly prohibited. I have found one place where the field name rule may not be enforced properly. It appears that csv2rec will use a noncompliant column name from a CSV file header as a key even in strict mode; however, rec2csv or relset will not accept the output it generates as input. I.e., echo "Österreich_population\n8.58" | csv2rec --strict | rec2csv blows up on rec2csv rather than on csv2rec (which is what I think should happen).
