failure with non-ASCII names

[dlove]

Passing qsub a non-ASCII job name (for instance), it reports

Unable to run job: Error reading answer list from qmaster.

whereas a forbidden ASCII character reports, say

Unable to run job: At ('@') not allowed in objectname.

but tracing verify_str_key shows it returning the same in each case, so
the job verification step returns false.

Also occurs with a space in the name, even though space seems to be checked the same as @.
