Hi folks,

I am trying to convert to using LuaJIT from Lua5.1 and hit this error in
one of the Lua modules.

As I stated in the subject above LuaJIT is throwing an invalid escape
sequence exception on a sequence that Lua5.1 accepts.

The string that causes the problem is '[^%w\-_ ]'.

Is this a known problem? Is there a workaround apart from deleting the
backslash?

Hi, it should be %-, not \-. Backslash should only be used for characters like \t.
