    <p>According to the <a href="http://docs.python.org/library/functions.html#open" rel="noreferrer">documentation for <code>open()</code></a>, you should add a <code>U</code> to the mode:</p> <pre><code>open('textbase.txt', 'Ur') </code></pre> <p>This enables "<a href="http://www.python.org/dev/peps/pep-0278/" rel="noreferrer">universal newlines</a>", which normalizes them to <code>\n</code> in the strings it gives you.</p> <p>However, the correct thing to do is to decode the UTF-16BE into Unicode objects <em>first</em>, before translating the newlines. Otherwise, a chance <code>0x0d</code> byte could get erroneously turned into a <code>0x0a</code>, resulting in</p> <blockquote> <p>UnicodeDecodeError: 'utf16' codec can't decode byte 0x0a in position 12: truncated data.</p> </blockquote> <p>Python's <a href="http://docs.python.org/library/codecs.html" rel="noreferrer"><code>codecs</code> module</a> supplies an <code>open</code> function that can decode Unicode and handle newlines at the same time:</p> <pre><code>import codecs for line in codecs.open('textbase.txt', 'Ur', 'utf-16be'): ... </code></pre> <p>If the file has a byte order mark (BOM) and you specify <code>'utf-16'</code>, then it detects the endianness and hides the BOM for you. If it does not (since the BOM is optional), then that decoder will just go ahead and use your system's endianness, which probably won't be good.</p> <p>Specifying the endianness yourself (with <code>'utf-16be'</code>) will not hide the BOM, so you might wish to use this hack:</p> <pre><code>import codecs firstline = True for line in codecs.open('textbase.txt', 'Ur', 'utf-16be'): if firstline: firstline = False line = line.lstrip(u'\ufeff') </code></pre> <p>See also: <a href="http://www.amk.ca/python/howto/unicode" rel="noreferrer">Python Unicode HOWTO</a></p>

    1. CO+1 for the solution rather than just the analysis (as in my answer) - you were too fast for me :-)

    2. COSolves the problem, python now sees all the lines. Thank you so much: I love this site :)

    3. CO@AP257: do they also decode properly? If it's really UTF-16BE, there'll be zero byte in front of every line, since Python's file object is encoding-unaware and just splits on newline characters. IMHO, you'll have to decode the file (by using the codecs module) properly before splitting into lines is possible.

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.
