I want to I check whether a string is in ASCII or not. I am aware of ord(), however when I try ord(‘é’), I have TypeError: ord() expected a character, but string of length 2 found.

How can I convert these safely to symbols that can be used in HTML source? Currently I’m converting everything to Unicode on the way in, … Read more
I got an error with the following exception message: UnicodeEncodeError: ‘ascii’ codec can’t encode character u’\ufeff’ in position 155: ordinal not in range(128) Not sure what u’\ufeff’ is, it shows up when I’m web scraping.

I’m trying the following, … Read more
I’d like to add the Unicode skull and crossbones to my shell prompt (specifically the ‘SKULL AND CROSSBONES’ (U+2620)), but I can’t figure out the magic incantation to make echo spit it, or any other, 4-digit Unicode character. Two-digit one’s are easy. For example, echo -e “\x55”, . In addition to the answers below it … Read more
Here is some code that I found on the Internet: class M{public static void main(String[]a){System.out.print(new char[] {‘H’,’e’,’l’,’l’,’o’,’ ‘,’W’,’o’,’r’,’l’,’d’,’!’});}} This code prints Hello World! onto the screen; you can see it run here.
