Can't handle binary data in output streams

[natefoo]

e.g. someone ran a zip file through cutadapt, so the tool stderr contains:

Output will be written into the directory: /jetstream2/scratch/main/jobs/53509211/working/
File seems to be in SOLiD colorspace format which is not supported by Trim Galore (sequence is: '�Vn)}}%u`:�ᰱ��g/߶m
�)! Please use Cutadapt on colorspace files separately and check its documentation!                               o�<?v�yԩ(A��ФZ�5_hf/���/��η��mgz8;���6xv�M��=c7�z͛_Z�L������^���u]W���7|̍ߦ~��KF2-��b

This results in the following from Pulsar:

Exception in thread [manager=jetstream2]-[action=postprocess]-[job=53509211]:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd1 in position 603: invalid continuation byte

This also results in a permanently non-terminal job.
