### sqlite utf8 encoding error

• Email
• Follow

I have an application that uses sqlite3 to store job/error data.  When
I log in as a German user the error codes generated are translated into
German.  The error code text is then stored in the db.  When I use the
fetchall() to retrieve the data to generate a report I get the
following error:

Traceback (most recent call last):
File "c:\Pest3\Glosser\baseApp\reportGen.py", line 199, in
OnGenerateButtonNow
self.OnGenerateButton(event)
File "c:\Pest3\Glosser\baseApp\reportGen.py", line 243, in
OnGenerateButton
warningresult =3D messagecursor1.fetchall()
UnicodeDecodeError: 'utf8' codec can't decode bytes in position 13-18:
unsupported Unicode code range

does anyone have any idea on what could be going wrong?  The string
that I store in the database table is:

'Keinen Text f=FCr =DCbereinstimmungsfehler gefunden'

I thought that all strings were stored in unicode in sqlite.

did you pass in a Unicode string or an 8-bit string when you stored the text ?

Greg Miller enlightened us with:
> 'Keinen Text f�r �bereinstimmungsfehler gefunden'

You posted it as "Keinen Text f<FC>r ...", which is Latin-1, not
UTF-8.

> I thought that all strings were stored in unicode in sqlite.

Only if you put them into the DB as such. Make sure you're inserting
UTF-8 text, since the DB won't do character conversion for you.

I cann't wait for the moment when encoded strings go away from Python.
The more I program in this language, the more confusion this difference
is causing. Now most of functions and various object's methods accept
strings and unicode, making it hard to find sources of Unicode*Errors.

Library writers can speed up the transition by hiding 8bit interface,
for example:

import sqlite
sqlite.I_promise_to_pass_8bit_string_only_in_utf8_encoding(my_signature=3D"=
sig.gif")

if you don't call this function 8bit strings will not be accepted :)
IMHO if libraries keep on excepting both str and unicode till python
3=2E0, it will just prolong the confusion of unicode newbies instead of
guiding them in the right direction _right now_.

No, they are stored as UTF-8 in sqlite and pysqlite has no way to make
sure the string you insert into the database is really encoded in
UTF-8 (the only secure way is to use Unicode strings).

How did you insert that string?

As a partial solution, try to disable automatic conversion of text
fields in Unicode strings:

def convert_text(s):
# XXX do not use Unicode
return s

# Register the converter with SQLite
sqlite.register_converter("TEXT", convert_text)

....connect("...",
detect_types=sqlite.PARSE_DECLTYPES|sqlite.PARSE_COLNAMES
)

Thank you for all your suggestions.  I ended up casting the string to
unicode prior to inserting into the database.

Don't do it by hand if it can be done by an automated system.

Try with:

from pysqlite2 import dbapi2 as sqlite

# if you have declared this encoding at begin of the module
return s.decode("iso-8859-1")

Thanks again, I'll look into this method.

UTF8 encoding
Hi Guys, It's been a long time since I've been using Dolphin but I'm glad to be back!

[ENCODING] UTF8 hell
Hello, I'm trying to deal with Ruby flaws with encoding, which I thought would be almost past with Ruby 1.9. I managed to find a solution for Ruby 1.8 and thought I did for Ruby 1.9...but in fact, no ! I fetch rows from an UTF8 database and try to work with the string. To do so, I would like it to be UTF8 encoded. "str.encoding()" gives me "ASCII-8BIT"...so, I thought one of these lines would solve the problem str.replace(Iconv.iconv("UTF8", "ascii", self).join()) OR self.encode!('UTF-8') But they don't !

Text in a textarea as far as JavaScript in the HTML document sees it is just a string of characters where those characters in modern browsers (where modern means Netscape 4.06 and later and IE 4 and later) are Unicode characters. Only a byte stream could be tested to conform to a particular encoding like UTF-8 so I don't think you question makes any sense as script in a browser...

utf8 encoding problem
Hi, I am retrieving a string from a txt file. The file contains some utf8 characters. I am comparing these characters against a default string. The problem is that some of the characters are not stored in a default format. For example: A is stored as Ａ Naturally when I compare the character it fails. Strangely when I unpacked the character it appears as 65313 which is the correct utf8 number for A. Any way around this? thanks. -- Posted via http://www.ruby-forum.com/.

Passing this through urllib.unquote does not help: >>> urllib.unquote(u't%C3%A9st') u't%C3%A9st' The problem turned out to be that urllib.unquote() process processes its input character by character which breaks when it tries to call chr() for a character: ...

I am consuming an XML feed, which continually contains invalid uft8 encoded characters. Time and time again the publisher of the feed has *fixed* the issue, but still they slip through.
