    <p>I did a quick testing with Perl 1.12.2 for MSWin32 Template module. It could handle all these substr operation properly. </p> <p>This is my test code:</p> <pre><code>use Template; # some useful options (see below for full list) my $config = { # DEFAULT_ENCODING =&gt; 'utf-8', INCLUDE_PATH =&gt; 'd:/devel/perl', # or list ref INTERPOLATE =&gt; 1, # expand "$var" in plain text EVAL_PERL =&gt; 1, # evaluate Perl code blocks }; # create Template object my $template = Template-&gt;new($config); # define template variables for replacement my $vars = { var1 =&gt; "abcdef" }; # specify input filename, or file handle, text reference, etc. my $input = 'ttmyfile.txt'; # process input template, substituting variables print $template-&gt;process($input, $vars); </code></pre> <p>ttmyfile.txt </p> <pre><code>Var = [% var1 %] [% string = "fööbär" -%] [% string.length %] # prints 6 [% string.substr(0, 5) %] # prints "fööbä" [% string.substr(0, 4) %] # prints "fööb" </code></pre> <p>Output:</p> <pre><code>Var = abcdef 6 # prints 6 fööbä # prints "fööbä" fööb # prints "fööb" 1 </code></pre> <p>All works fine, even without <code>use utf8</code> nor <code>DEFAULT_ENCODING</code>. Key things here:</p> <ol> <li><p>Make sure your template <code>.tt</code> files are encoded as UTF8 with <a href="http://linuxyz.blogspot.com/search/label/i18n" rel="nofollow">BOM -- <code>Byte Order Mark</code></a>. This is a must do task! Because Template-Toolkit is detect the Unicode file encoding according to BOM. </p> <ul> <li>You can use Windows Notepad to save a file with BOM, just do <code>File</code> --> <code>Save</code> --> Encoding: "UTF-8". </li> <li>You can use VIM make it as well by input <code>set fenc=utf8</code> and <code>set bomb</code>, then save the file, the file will start with BOM. </li> </ul></li> <li><p>Set the <code>NCODING</code> paramter <code>Template-&gt;new({NCODING =&gt; 'utf-8'});</code> as 'utf-8' will enforce <code>Template</code> to load template file as 'utf-8'.</p></li> <li><p>Suggest to have <code>use utf8</code> in your script, it will ensure all your inline strings are encoding as utf8 properly.</p></li> </ol> <p>Because <code>Catalyst::View::TT</code> rely on Template, I believe it should be working as well! Good luck~~~</p>

    1. COThank you for the example. Unfortunately it doesn't work for me:( I saved the files as UTF8 without BOM and the `fööb` line reads `fö?` and `length` prints 9 instead of 6. Afterwards I saved both files with BOM and length kept 6 but all umlauts turned into question marks. I got the feeling it could be problem with my system. I'll determine this. OS is Fedora 14 KDE Spin. I have no encoding problems anywhere else.

    2. COGood, you have got the right thing! the question marks is caused by your terminal rather than the encoding itself. You can simply redirect the output to a file, and check the file with your editor. It will be right things you want!

    3. CONo, UTF-8 is not supposed to have a BOM.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
