I want to unescape "Sch%C3%B6ne". I found this unescape function online that works in a lot of cases but not this one because it's 2 characters for one, I tested the following code on http://www.lua.org/cgi-bin/demo
teststring = "Sch%C3%B6ne"
function unescape (str)
str = string.gsub (str, "+", " ")
str = string.gsub (str, "%%(%x%x)", function(h) return string.char(tonumber(h,16)) end)
str = string.gsub (str, "\r\n", "\n")
return str
end
print(unescape(teststring))
It prints Schöne but I want Schöne. Any one can help me?
The method works fine, it's the online Lua interpreter that doesn't show correct result in this UTF8 example.
You can test it under another interpreter, e.g, this one.
