Note that iso-8859-1 is a unicode encoding -- it just doesn't support all of the characters.

I don't know what you mean by "unicode encoding" (are there encodings that map to non-unicode chars?), but in the perl context it's worth mentioning that iso-8859-1 strings don't follow unicode-semantics by default, the need to be encoded like any other string:

# this file is stored as latin1 
print "ä" =~ m/\w/ ? "Unicode\n" : "Bytes\n";
__END__
Bytes

Perl's unicode support is great, but the programmer MUST learn the difference between unicode and utf-8, and the difference between text data and binary data.

Yes, and they have to learn that for any kind of tool that supports Unicode and different encodings.

And I really like the Perl 6 spec which allows string operations on byte, codepoint and grapheme level ;-)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
