    <p>**** This answer lead to a new gem: <a href="http://rubygems.org/gems/file_with_bom" rel="noreferrer">file_with_bom</a> ****</p> <p>I had the similar problem in the past and I extended <code>File.open</code> with additional encoding variants for the <code>w</code>-mode:</p> <pre><code>class File BOM_LIST_hex = { Encoding::UTF_8 =&gt; "\xEF\xBB\xBF", #"\uEFBBBF" Encoding::UTF_16BE =&gt; "\xFE\xFF", #"\uFEFF", Encoding::UTF_16LE =&gt; "\xFF\xFE", Encoding::UTF_32BE =&gt; "\x00\x00\xFE\xFF", Encoding::UTF_32LE =&gt; "\xFE\xFF\x00\x00", } BOM_LIST_hex.freeze def utf_bom_hex(encoding = external_encoding) BOM_LIST_hex[encoding] end class &lt;&lt; self alias :open_old :open def open(filename, mode_string = 'r', options = {}, &amp;block) #check for bom-flag in mode_string options[:bom] = true if mode_string.sub!(/-bom/i,'') f = open_old(filename, mode_string, options) if options[:bom] case mode_string #r|bom already standard since 1.9.2 when /\Ar/ #read mode -&gt; remove BOM #remove BOM bom = f.read(f.utf_bom_hex.bytesize) #check, if it was really a bom if bom != f.utf_bom_hex.force_encoding(bom.encoding) f.rewind #return to position 0 if BOM was no BOM end when /\Aw/ #write mode -&gt; attach BOM f = open_old(filename, mode_string, options) f &lt;&lt; f.utf_bom_hex.force_encoding(f.external_encoding) end #mode_string end if block_given? yield f f.close end end end end #File </code></pre> <p>Testcode:</p> <pre><code>EXAMPLE_TEXT = 'some content öäü' File.open("file_utf16le.txt", "w:utf-16le|bom"){|f| f &lt;&lt; EXAMPLE_TEXT } File.open("file_utf16le.txt", "r:utf-16le|bom:utf-8"){|f| p f.read } File.open("file_utf16le.txt", "r:utf-16le:utf-8", :bom =&gt; true ){|f| p f.read } File.open("file_utf16le.txt", "r:utf-16le:utf-8"){|f| p f.read } File.open("file_utf8.txt", "w:utf-8", :bom =&gt; true ){|f| f &lt;&lt; EXAMPLE_TEXT } File.open("file_utf8.txt", "r:utf-8", :bom =&gt; true ){|f| p f.read } File.open("file_utf8.txt", "r:utf-8|bom", ){|f| p f.read } File.open("file_utf8.txt", "r:utf-8", ){|f| p f.read } </code></pre> <p>Some remarks:</p> <ul> <li>The code is from pre 1.9-times (but it still works).</li> <li>I used <code>-bom</code> as a bom indicator (ruby 1.9 uses <code>|bom</code>.</li> </ul> <p>Some needed fixes to be better:</p> <ul> <li>use <code>|bom</code> instead <code>-bom</code></li> <li>use the standard <code>r|bom</code> for reading</li> <li>make it ruby 1.8 and 1.9 enabled</li> </ul> <p>Perhaps I will find some time tomorrow to refactor my code and provide it as a gem.</p>

    2. CO+1 for the gem. I guess you could contact the Ruby or Rubinius guys and made it merged into official distribution.

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.
