Is it possible to convert a string to unicode characters in Python?
For example: Hello => \u0048\u0045\u004C\u004C\u004F

You can't. A string already consists of 'Unicode characters'. What you want to change is not its representation but its actual contents.
That, fortunately, is as simple as
import re
text = 'Hello'
print (re.sub('.', lambda x: r'\u%04X' % ord(x.group()), text))
which outputs
\u0048\u0065\u006C\u006C\u006F

Thank you! What is this conversion called? I've been googling for almost an hour now. I would assume this has already been asked and been answered somewhere.

It's a regular expression that replaces each character with its own Unicode string through a custom replacement function. But there are several other approaches possible – this is only one. The basic idea is that each character gets replaced with another string.

I know it's a regular expression and it's using a custom replacement function, I was just asking about converting character H to \u0048..

print(''.join(r'\u{:04X}'.format(ord(char)) for char in 'Hello'))Bravi
@furas I like that version too, looks pythonic. :)
