    <p>In the notation</p> <pre><code>u'Capit\xe1n\n' </code></pre> <p>the "\xe1" represents just one byte. "\x" tells you that "e1" is in hexadecimal. When you write</p> <pre><code>Capit\xc3\xa1n </code></pre> <p>into your file you have "\xc3" in it. Those are 4 bytes and in your code you read them all. You can see this when you display them:</p> <pre><code>&gt;&gt;&gt; open('f2').read() 'Capit\\xc3\\xa1n\n' </code></pre> <p>You can see that the backslash is escaped by a backslash. So you have four bytes in your string: "\", "x", "c" and "3".</p> <p>Edit:</p> <p>As others pointed out in their answers you should just enter the characters in the editor and your editor should then handle the conversion to UTF-8 and save it.</p> <p>If you actually have a string in this format you can use the <code>string_escape</code> codec to decode it into a normal string:</p> <pre><code>In [15]: print 'Capit\\xc3\\xa1n\n'.decode('string_escape') Capitán </code></pre> <p>The result is a string that is encoded in UTF-8 where the accented character is represented by the two bytes that were written <code>\\xc3\\xa1</code> in the original string. If you want to have a unicode string you have to decode again with UTF-8.</p> <p>To your edit: you don't have UTF-8 in your file. To actually see how it would look like:</p> <pre><code>s = u'Capit\xe1n\n' sutf8 = s.encode('UTF-8') open('utf-8.out', 'w').write(sutf8) </code></pre> <p>Compare the content of the file <code>utf-8.out</code> to the content of the file you saved with your editor.</p>

    1. COSo, what's the point of the utf-8 encoded format if python can read in files using it? In other words, is there any ascii representation that python will read in \xc3 as 1 byte?

    2. COThe answer to your "So, what's the point…" question is "Mu." (since Python can read files encoded in UTF-8). For your second question: \xc3 is not part of the ASCII set. Perhaps you mean "8-bit encoding" instead. You are confused about Unicode and encodings; it's ok, many are.

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.
