When checking out repo to Windows environment, some files in test
fixture file trees do not get checked out. By setting renaming those
files with an urlencoded name, and populating a temporary directory
with corresponding file structure and decoded filenames during test by
a fixtures script, this will not cause checkout problems for those who
want to read the repo in Win environment
