( #3333=superdoc: print w/replies, xml ) Need Help??

but I have no evidence of NonspacingMark ever being in the normalized string.

There are three in the example you gave:

use strict;
use warnings qw( all );
use feature qw( say );

use utf8;
use open ':std', ':encoding(UTF-8)';

use charnames          qw( );
use Unicode::Normalize qw( NFKD );

my $html = "Lubomír,Bartoňová";
my $decomposedHtml = NFKD( $html );
say charnames::viacode(ord($_))
   for $decomposedHtml =~ /(\p{NonspacingMark})/g;

Output:

COMBINING ACUTE ACCENT COMBINING CARON COMBINING ACUTE ACCENT

The code you posted is a hack to find an ASCII "equivalent" to the input.

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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 or How to display code and escape characters are good places to start.
