VirtualMachinePool.info() not working

[mpvillerius]

code :

#!/usr/bin/python
from __future__ import unicode_literals
import oca
# OpenNebula credentials
CREDENTIALS = "x:x"
# XML_RPC endpoint where OpenNebula is listening
ENDPOINT    = "http://ui.hpccloud.surfsara.nl:2633/RPC2"
client = oca.Client(CREDENTIALS, ENDPOINT)
hpc_version=client.version()
print "Surf Sara HPC cloud Version : " + hpc_version
VM_pool = oca.VirtualMachinePool(client)
print "VirtualMachinePool :" + str(VM_pool)

Prints (vmpool empty):
Surf Sara HPC cloud Version : 4.14.2
VirtualMachinePool :[]

Now add the code print VM_pool.info() gives an error:

Surf Sara HPC cloud Version : 4.14.2
VirtualMachinePool :[]
root@ubuntu:~/myproject# vi hpc-overview.py 
root@ubuntu:~/myproject# python ./hpc-overview.py

UnicodeEncodeError: 'ascii' codec can't encode character u'\u200b' in position 3728: ordinal not in range(128)

I am on the master branch (oca==4.15.0a1)

Am I doing something wrong?

[markus-sara]

No, this is a limitation in the transcoding algorithm. Char '\u200b' is one of the unicode zero-width characters. Maarten-k has submitted pull request 5e20583 that fixes the problem for this particular character occurrence.

[sysradium]

Maybe it's better to add an encode('utf-8') statement?

[markus-sara]

Yes, a more structural solution is needed. Your solution sounds better and when I get round to it I will test if that solves the general problem. Do not hold your breath, though :-)

[sysradium]

@markus-sara ok, feel free submit a PR 👍
I do not have some installed OpenNebula instance, so can't try if it really works, so would be cool to hear from you.
