[luatex] Off topic: A quiz

[Patrick Gundlach]

Hi all,

this has to do with the discussion we had about the selene unicode library a 
few years ago. Here is a quiz for you. You might think about it first, before 
trying it out. 

----------------------------------
match = unicode.utf8.match

if match("à","%s") then
    print("space")
else
    print("not a space")
end

if match("á","%s") then
    print("space")
else
    print("not a space")
end
----------------------------------


Now, what is printed?
