As Travis Brown indicated in a comment, you have to import the ord function from the module Data.Char: import Data.Char (ord) main = print (ord ‘a’) Only the Prelude module is loaded by default, all other modules have to be imported explicitly.
$ str=”hello” $ hex=”$(printf ‘%s’ “$str” | xxd -p -u)” $ echo “$hex” 68656C6C6F Or: $ hex=”$(printf ‘%s’ “$str” | hexdump -ve ‘/1 “%02X”‘)” $ echo “$hex” 68656C6C6F Careful with the ‘”%X”‘; it has both single quotes and double quotes.
In Python 2 – Turn it into a string first, then into unicode. str(integer).decode(“utf-8”) Best way I think. Works with any integer, plus still works if you put a string in as the input. Updated edit due to a comment: For Python 2 and 3 – This works on both but a bit messy: str(integer).encode(“utf-8”).decode(“utf-8”)
Just cast each character to an int: for (int i = 0; i < str.length; i++) Console.Write(((int)str[i]).ToString());
You could always add a reference to Microsoft.VisualBasic and then use the exact same methods: Strings.Chr and Strings.Asc. That’s the easiest way to get the exact same functionality.
Unicode is a way to assign unique numbers (called code points) to characters from nearly all languages in active use today, plus many other characters such as mathematical symbols. There are many ways to encode Unicode strings as bytes, such as UTF-8 and UTF-16. ASCII assigns values only to 128 characters (a-z, A-Z, 0-9, space, … Read more
The String#ord method will do the trick: ruby-1.9.2-p136 > ‘x’.ord => 120 ruby-1.9.2-p136 > ‘0’.ord => 48 ruby-1.9.2-p136 > ‘ ‘.ord => 32
I think this will do the trick: SELECT REGEXP_REPLACE(COLUMN, ‘[^[:print:]]’, ”)
