perlquestion Jim <p>In the documentation of [href://http://search.cpan.org/~hmbrand/Text-CSV_XS-0.94/CSV_XS.pm#SPECIFICATION|Text::CSV_XS], there's a peculiar reference to what seems like a very special case:</p> <blockquote>The separation-, escape- &#91;<i>sic</i>&#93;, and escape- characters can be any ASCII character in the range from 0x20 (space) to 0x7E (tilde). Characters outside this range may or may not work as expected. &hellip; If you use perl-5.8.2 or higher, these three attributes are utf8-decoded, to increase the likelihood of success. <b>This way U+00FE will be allowed as a quote character.</b> &#91;My emphasis.&#93</blockquote> <p>Why is this particular Unicode character, <tt>LATIN SMALL LETTER THORN</tt>, singled out for special mention in the documentation? And why does it state that "&#91;c&#93;haracters outside &#91;the range from 0x20 through 0x7E&#93; may or may not work as expected"? When <i>might</i> they work?</p> <p>The implication of this explicit mentioning of <tt>U+00FE</tt> in the documentation is that [mod://Text::CSV_XS] can be used to parse CSV records in Unicode Concordance DAT files. If this is the case, then I want to learn how to do this. (See my earlier post titled [1007942|Best Way To Parse Concordance DAT File Using Modern Perl?])</p> <p>Jim</p>
