    <p><strong>Update:</strong> this error can be reproduced simply by running this from the command line:</p> <pre><code>scrapy shell http://www.indiegogo.com/Straight-Talk-About-Your-Future </code></pre> <hr> <p>I'm using Scrapy to crawl a website. Every page I scrape claims to be encoded UTF-8:</p> <pre><code>&lt;meta content="text/html; charset=utf-8" http-equiv="Content-Type"&gt; </code></pre> <p>But occasionally, the pages contain bytes that fall outside of UTF-8, and I get Scrapy errors like:</p> <pre><code>exceptions.UnicodeDecodeError: 'utf8' codec can't decode byte 0xe8 in position 131: invalid continuation byte </code></pre> <p>I still need to scrape these pages, even though they contain unmappable characters. Is there a way to tell Scrapy to override the page's declared encoding, and use another (say, UTF-16) instead?</p> <p>Here's where the exception is being caught:</p> <pre><code>2012-05-30 14:43:20+0200 [igg] ERROR: Spider error processing &lt;GET http://www.site.com/page&gt; Traceback (most recent call last): File "/Library/Python/2.7/site-packages/twisted/internet/base.py", line 1178, in mainLoop self.runUntilCurrent() File "/Library/Python/2.7/site-packages/twisted/internet/base.py", line 800, in runUntilCurrent call.func(*call.args, **call.kw) File "/Library/Python/2.7/site-packages/twisted/internet/defer.py", line 368, in callback self._startRunCallbacks(result) File "/Library/Python/2.7/site-packages/twisted/internet/defer.py", line 464, in _startRunCallbacks self._runCallbacks() --- &lt;exception caught here&gt; --- File "/Library/Python/2.7/site-packages/twisted/internet/defer.py", line 551, in _runCallbacks current.result = callback(current.result, *args, **kw) File "/Library/Python/2.7/site-packages/scrapy/core/spidermw.py", line 61, in process_spider_output result = method(response=response, result=result, spider=spider) </code></pre>

    1. CODepending on where this happens, you could add my_string.encode('utf8') to circumvent this error.

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.
