How do you compose an unescaped Unicode string in Haskell by parsing the escaped string?-CodePudding

I am parsing some text which might be "\u3200". Parsing this and converting to decimal, I know the integer sequence should be 12800. Now, I want to put this back together; I might do the following:

toPrintedChar x = return "\\x"    x

However, this returns an escaped sequence, and will not print the Unicode character associated with it. It is unclear to me how I can create a new string which does not have the escaped character.

I can create the string myself:

toPrintedChar x = return "\x12800"

and this does print the Unicode representation. I am wondering how I can do this generally? Thanks!

CodePudding user response：

To convert an integer value into a string made of that Unicode code point, it is enough to convert the number into a Char and then put it in a list. E.g.,

myString :: String
myString = [ toEnum 12800 ]
