I think the problem is a bad interaction between your language
environment and the file in question.

Does the following command load vline.el successfully?

emacs -Q --eval '(let ((coding-system-for-read (quote utf-8)))
(load-file "path/to/vline.el"))'

?

For me, the above works regardless of my LANG environment
variable however:

LANG=en_US emacs -Q --eval '(load-file "path/to/vline.el")'

Loading /Home/s0198183/tmp/vline.el (source)...
Invalid read syntax: "?"

In this case, emacs uses the iso-latin-1 coding-system to open
the file and barfs when trying to read the utf-8 character in it.

Cheers,
Lawrence
