Why I need to use += and also convert the user inputted word into str? Isn't += is like unicode = unicode + str(ord(char))? I don't see the impact of += here why can't I just use =. And if I thought that the user inputted message is already a string? Why do I need to convert it into str again?

The Unicode converter doesn't automatically add spaces between the converted values. You can use the add spaces button to separate the Unicode characters so that the converted values will also be separated from one another.
