    <p>Let's fire up the old standby, IDLE, and see if we can replicate what you're seeing.</p> <pre><code>IDLE 1.1.4 &gt;&gt;&gt; a = u'può essere / sarà / 日本' Unsupported characters in input &gt;&gt;&gt; a = u'pu\xf2 essere / sar\xe0 / \u65e5\u672c' &gt;&gt;&gt; b = a.encode('utf-8') &gt;&gt;&gt; a u'pu\xf2 essere / sar\xe0 / \u65e5\u672c' &gt;&gt;&gt; b 'pu\xc3\xb2 essere / sar\xc3\xa0 / \xe6\x97\xa5\xe6\x9c\xac' &gt;&gt;&gt; print a può essere / sarà / 日本 &gt;&gt;&gt; print b può essere / sarà / 日本 </code></pre> <p>Note that I see something different when I print <code>b</code>. This is because my shell (IDLE) does not interpret a sequence of bytes as UTF-8 text, but rather uses my platform character encoding, cp1252.</p> <p>Let's just double check this.</p> <pre><code>&gt;&gt;&gt; import sys &gt;&gt;&gt; sys.stdout.encoding 'cp1252' </code></pre> <p>Yup, that's why I get different behavior than you do. Because your sys.stdout.encoding is UTF-8. And that is why, despite <code>a</code> and <code>b</code> being completely different values, they display the same; your terminal interprets bytes as UTF-8.</p> <p>So you might be wondering if we can convert our sequence of unicode characters <code>a</code> into a sequence of bytes that can be displayed in IDLE</p> <pre><code>&gt;&gt;&gt; c = a.encode('cp1252') Traceback (most recent call last): File "&lt;pyshell#19&gt;", line 1, in -toplevel- c = a.encode('cp1252') #uses default encoding File "C:\Python24\lib\encodings\cp1252.py", line 18, in encode return codecs.charmap_encode(input,errors,encoding_map) UnicodeEncodeError: 'charmap' codec can't encode characters in position 20-21: character maps to &lt;undefined&gt; </code></pre> <p>The answer is no; <a href="http://en.wikipedia.org/wiki/Windows-1252" rel="nofollow">cp1252</a> does not support encoding Chinese characters as bytes.</p>

    1. COSo you could print a because python's print detects it's an UTF-8 string and converts it to cp1252? Whereas it just translates b as a cp1252 encoded string?

    2. CONo, I can print `a` because `a` is a sequence of (16 bit) unicode characters. But `b` is a sequence of *bytes*, and thus python needs to convert it to characters, and does so using the platform-default encoding, cp1252

    3. COMy version of IDLE uses UTF-8. Unfortunately I can't duplicate the test either because it's applying some kind of encoding to the *input*.

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.

SQuiL has stopped working due to an internal error.
