NAME
    XML::Char - validate characters for XML

SYNOPSIS
        use XML::Char;
        if (not XML::Char->valid("bell ".chr(7))) {
            die 'no way to store this string directly to XML';
        }
    
        use utf8;
        use XML::Char;
        if (XML::Char->valid("UTF8 je pořádný peklo")) {
            print "fuf, we are fine\n";
        }

DESCRIPTION
    For me it was kind of a surprised to learn that `char(0)' is a valid
    UTF-8 character. All of the 0-0x7F are...

        Emo: well it's not because that they are valid utf-8 characters that you have to expect XML to accept them

    Well of course not, now I know :-)

    http://www.w3.org/TR/REC-xml/#charsets defines which characters XML
    processors MUST accept:

        [2]         Char       ::=          #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]
        /* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF. */

    This module validates if a given string meets this criteria. In addition
    the string has to be a Perl UTF-8 string (`is_utf8_string()' - see
    perlapi).

  valid($value)
    Returns true or false if `$value' consists of valid UTF-8 XML
    characters.
