A Concordance DAT file is simply a CSV text file that uses the following metacharacters:
- U+0014 Field Separator ("Comma") [DEVICE CONTROL FOUR]
- U+00FE String Delimiter ("Quote") [LATIN SMALL LETTER THORN]
- U+00AE Newline Placeholder ("Newline") [REGISTERED SIGN]
What's the best way to parse a Concordance DAT file using Modern Perl?
Assume the following:
- The file is in the UTF-8 character encoding form of Unicode
- The file has the Unicode byte order mark in it (U+FEFF), which must be handled properly
- Records are terminated by <CR><LF> pairs
- Despite the newline placeholder convention, fields can have literal <CR>, <LF>, and paired <CR><LF> characters in them
- The text in fields can be arbitrarily large (many megabytes)
