Bug Description

Debian 9.4, python 2.7.13, hplip 3.18.3
On hp-toolbox gui if status page is choosen, the application crashes.

Traceback (most recent call last):
  File "/usr/share/hplip/ui5/devmgr5.py", line 569, in Tabs_currentChanged
    self.TabIndex[tab]()
  File "/usr/share/hplip/ui5/devmgr5.py", line 1315, in updateStatusTab
    self.updateStatusTable()
  File "/usr/share/hplip/ui5/devmgr5.py", line 1410, in updateStatusTable
    tt = str("%s %s"%(dt.toString(),desc))
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe1' in position 3: ordinal not in range(128)

Traceback (most recent call last):
  File "/usr/share/hplip/ui5/devmgr5.py", line 569, in Tabs_currentChanged
    self.TabIndex[tab]()
  File "/usr/share/hplip/ui5/devmgr5.py", line 1315, in updateStatusTab

  File "/usr/share/hplip/ui5/devmgr5.py", line 1431, in updateStatusTable
    i = QTableWidgetItem(str(t))
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe1' in position 3: ordinal not in range(128)

devmgr5.py
line 1410 >> tt = str("%s %s"%(dt.toString(), desc))
line 1431 >> i = QTableWidgetItem(str(t))

In this line the coercing to string is not work because the values can contain unicode characters.
Using "to_uncode" function (from the sourcecode of hplip) in these cases will solve the problem.

By-the-way Can I found the source code somewhere, perhaps I could file a PR?

Hi,

Debian 9.4 is not yet supported by HPLIP , so some functionalities might fail . Please use any previous versions of Debian.you can download supported hplip version source code from this link.
https://sourceforge.net/projects/hplip/files/hplip/
Debian 9.4 will be supported by HPLIP in the future release.

Thanks,
Shivani mandora.

Changed in hplip:

I confirm what ~charisz said

changing from str() to to_unicode() in lines 1409 and 1431 fixes this issue.
