nDisplay failed to launch with a user name account which contains non-ASCII chars

create a user account w/ Chinese or Japanese Hanzi on one of the nDisplay render node

then try to launch nDisplay as usual

nDisplay fail to launch

after switching to an English username, nDisplay could launch correctly.

NOTE: based on the log, SB listener seems try to copy files into <userName>/directory but when the user name contains non-ASCII chars, it seems failed to do so.
