[Bug] Encoding Non-Unicode Prompt Characters

[guumaster]

If you this in the prompt: "in the style of zdzisław beksiński" it makes the plugin fail with this error:

UnicodeEncodeError
Python 3.8.1: D:\Program Files\Krita (x64)\bin\krita.exe
Sun Sep  4 13:54:27 2022

A problem occurred in a Python script.  Here is the sequence of
function calls leading up to the error, in the order they occurred.

 C:\Users\MY_USER\AppData\Roaming\krita\pykrita\koi\koi.py in pingServer(self=<koi.koi.Koi object>)
  121 
  122         # wait for response and read image
  123         with request.urlopen(r, timeout=60) as response:
  124             returned_image = QImage.fromData(response.read())
  125 
global request = <module 'urllib.request' from 'D:\\Program Files...x64)\\python\\python38.zip\\urllib\\request.pyc'>
request.urlopen = <function urlopen>
r = <urllib.request.Request object>
timeout undefined
response undefined

 d:\Program Files\Krita (x64)\urllib\request.py in urlopen(url=<urllib.request.Request object>, data=None, timeout=60, cafile=None, capath=None, cadefault=False, context=None)

...
UnicodeEncodeError: 'latin-1' codec can't encode character '\u0142' in position 78: ordinal not in range(256)
    __cause__ = None
    __class__ = <class 'UnicodeEncodeError'>
    __context__ = None
    __delattr__ = <method-wrapper '__delattr__' of UnicodeEncodeError object>
....
    __suppress_context__ = False
    __traceback__ = <traceback object>
    args = ('latin-1', 'a powerful wizard; cracked open sphere; glowing ...painting; magic the gathering art; fine detailed;', 78, 79, 'ordinal not in range(256)')
    encoding = 'latin-1'
    end = 79
    object = 'a powerful wizard; cracked open sphere; glowing ...painting; magic the gathering art; fine detailed;'
    reason = 'ordinal not in range(256)'
    start = 78
    with_traceback = <built-in method with_traceback of UnicodeEncodeError object>

The above is a description of an error in a Python program.  Here is
the original traceback:

thanks for making me aware of this--i'll have to see if there's a way to fix this issue--if not i'll just need to make an error dialogue for it.
