    <p>I have created a package using the encoding utf-8. </p> <p>When calling a function, it returns a <code>DataFrame</code>, with a column coded in utf-8.</p> <p>When using IPython at the command line, I don't have any problems showing the content of this table. When using the Notebook, it crashes with the error <code>'utf8' codec can't decode byte 0xe7</code>. I've attached a full traceback below.</p> <p>What is the proper encoding to work with Notebook?</p> <pre><code>UnicodeDecodeError Traceback (most recent call last) &lt;ipython-input-13-92c0011919e7&gt; in &lt;module&gt;() 3 ver = verif.VerificacaoNA() 4 comp, total = ver.executarCompRealFisica(DT_INI, DT_FIN) ----&gt; 5 comp c:\Python27-32\lib\site-packages\ipython-0.13.1-py2.7.egg\IPython\core\displayhook.pyc in __call__(self, result) 240 self.update_user_ns(result) 241 self.log_output(format_dict) --&gt; 242 self.finish_displayhook() 243 244 def flush(self): c:\Python27-32\lib\site-packages\ipython-0.13.1-py2.7.egg\IPython\zmq\displayhook.pyc in finish_displayhook(self) 59 sys.stdout.flush() 60 sys.stderr.flush() ---&gt; 61 self.session.send(self.pub_socket, self.msg, ident=self.topic) 62 self.msg = None 63 c:\Python27-32\lib\site-packages\ipython-0.13.1-py2.7.egg\IPython\zmq\session.pyc in send(self, stream, msg_or_type, content, parent, ident, buffers, subheader, track, header) 557 558 buffers = [] if buffers is None else buffers --&gt; 559 to_send = self.serialize(msg, ident) 560 flag = 0 561 if buffers: c:\Python27-32\lib\site-packages\ipython-0.13.1-py2.7.egg\IPython\zmq\session.pyc in serialize(self, msg, ident) 461 content = self.none 462 elif isinstance(content, dict): --&gt; 463 content = self.pack(content) 464 elif isinstance(content, bytes): 465 # content is already packed, as in a relayed message c:\Python27-32\lib\site-packages\ipython-0.13.1-py2.7.egg\IPython\zmq\session.pyc in &lt;lambda&gt;(obj) 76 77 # ISO8601-ify datetime objects ---&gt; 78 json_packer = lambda obj: jsonapi.dumps(obj, default=date_default) 79 json_unpacker = lambda s: extract_dates(jsonapi.loads(s)) 80 c:\Python27-32\lib\site-packages\pyzmq-13.0.0-py2.7-win32.egg\zmq\utils\jsonapi.pyc in dumps(o, **kwargs) 70 kwargs['separators'] = (',', ':') 71 ---&gt; 72 return _squash_unicode(jsonmod.dumps(o, **kwargs)) 73 74 def loads(s, **kwargs): c:\Python27-32\lib\json\__init__.pyc in dumps(obj, skipkeys, ensure_ascii, check_circular, allow_nan, cls, indent, separators, encoding, default, **kw) 236 check_circular=check_circular, allow_nan=allow_nan, indent=indent, 237 separators=separators, encoding=encoding, default=default, --&gt; 238 **kw).encode(obj) 239 240 c:\Python27-32\lib\json\encoder.pyc in encode(self, o) 199 # exceptions aren't as detailed.

    1. COI've had this happen when I had embedded smart quotes as values in either a index or column name. Not sure what encoding to use to get around it, but when I removed the smart quotes, the problem went away.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
