Much easier solution is to develop a standard for meta-field, which will describe CSV features used. Example:

    #!CSV: escape=:\\', quote='"', quotealg='c-like', separator='\t', eof='\n\r', comment='#', encoding='utf-8'
    foo     bar     baz

Such standard (Lets call it mCSV) can be incorporated into existing solutions. Moreover, existing files can be converted from/to a proprietary flavor of CSV to/from metainized CSV.
