Hello,
when I try to start a Dabo application I get this:
sib@gespenst-lubuntu:~/src/dabo-master/ide$ ./Editor.py
Traceback (most recent call last):

dabo.log.error(_("Could not connect to the Dabo servers: %s") % e)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 42:
ordinal not in range(128)
I've looked at this again and put some diagnostic print statements into
dApp.py. The Web update isn't really the problem, a mix of strings and
unicode objects is.
The _ function changes the message
"Could not connect to the Dabo servers: %s"
to a unicode object (without translating it, for whatever reason).
But printing the exception object e and its type gives this:
print (e, type(e))
(URLError(error(110, 'Die Wartezeit f\xc3\xbcr die Verbindung ist
abgelaufen'),), <class 'urllib2.URLError'>)
So the exception message is in German and contains the umlaut ü. And
it's a string, in the system character set UTF-8, not a unicode object.
I suppose this is directly from the system.
And the result of
x = u"some unicode %s" % "äöüß"
results in the UnicodeDecodeError, because we're using Python 2 here.
I strongly suspect similar problems at other places in the Dabo code; at
least I've intermittent unicode related errors I can't explain from my
own code.
So this should be fixed at some central place, but where?
Greetings,
Sibylle
