More interesting: any kind of delimiter, including chars from utf8 and windows-1252, and you need to detect encoding too. And CSV embedded in CSV, a result of flattening an XML source. And fixed width files, not CSV but where you see CSV you may need to support. And let's not get into date parsing or other typed data, and type inference over sample files.

Hi, q's creator here,

Any kind of input/output delimiter is supported (-d <delim> and -D <delim>), and also multiple encodings (-e <encoding>). Also, q performs automatic type inference over the actual data.

Encoding autodetection and fixed width files are not supported though.

The company I work for also does delimiter autodetection, quote character inference (from a limited set), and encoding inference (which is mostly limited to utf8 / windows-1252 / iso-8859-15, but it can't reliably differentiate latter two).
