Code of usernames with space does not compile

[niteshjain]

Valid code of users with username which have a space in them return a compile error
Steps to reproduce this :

• Create an account with a space in it like "user 01"
• Write any valid code in any language and submit

Output :

• Compile error

Expected Output:

• Either wrong answer or correct answer

This may be because directories are created based on the username for each user and in GNU/Linux based OS, space in a file/directory name need to be escaped (like so user\ 01)
A temporary fix might be to warn users not to create accounts with space in there username
