Questions tagged [unicode-literals]

is used in its general meaning, so make sure you provide a tag of your programming environment, if any, in your question.

For example in Python, quoting this answer:

A unicode literal ( u'some text' ) is a different type of Python object from a python byte string ( 'some text' ). It's like using \n versus \N ; the former has meaning in python literals (it's interpreted as a newline character), the latter just means a backslash and a capital N (two characters).
