Contents of a Unicode (UTF-8) text file named DriedMangos.txt:

dried mangos
mangues séchées
芒果幹
doraido mangōsu
ドライドマンゴス
ドライドマンゴス
ト"ライト"マンコ"ス

Perl script to demonstrate matching Unicode grapheme clusters using the regular expression backslash sequence \X:

#!perl use strict; use warnings; use autodie; open my $input_fh, '<:encoding(UTF-8)', 'DriedMangos.txt'; open my $output_fh, '>:encoding(UTF-8)', 'Graphemes.txt'; while (my $line = <$input_fh>) { chomp $line; while ($line =~ m/(\X)/g) { print $output_fh "[$1]"; } print $output_fh "\n"; } close $input_fh; close $output_fh;

Contents of the output text file named Graphemes.txt:

[d][r][i][e][d][ ][m][a][n][g][o][s]
[m][a][n][g][u][e][s][ ][s][é][c][h][é][e][s]
[芒][果][幹]
[d][o][r][a][i][d][o][ ][m][a][n][g][ō][s][u]
[ド][ラ][イ][ド][マ][ン][ゴ][ス]
[ド][ラ][イ][ド][マ][ン][ゴ][ス]
[ト]["][ラ][イ][ト]["][マ][ン][コ]["][ス]

(See http://ameblo.jp/gucciman-ikkob/entry-10317490092.html for an explanation of the peculiar last line of the file named DriedMangos.txt.)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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.
