Syntax: character literal contains multiple characters in Julia

I am trying to define a string in Julia like I would in Python by doing the following:

'hello world'

However, I am getting the following error:

ERROR: syntax: character literal contains multiple characters
Stacktrace:
 [1] top-level scope
   @ none:1

Any suggestion to resolve this? I searched around for the error but nothing about Julia came up, only C# and other languages.

Your answer is not complete without noting that in Julia you have also """

help?> """

  """ is used to delimit string literals. Strings created by triple quotation marks 
  can contain " characters without escaping and are dedented to the level of the
  least-indented line. This is useful for defining strings within code
  that is indented.

  Examples
  ≡≡≡≡≡≡≡≡≡≡

  julia> """Hello World!"""
  "Hello World!"

  julia> """Contains "quote" characters"""
  "Contains \"quote\" characters"

  julia> """
           Hello,
           world."""
  "Hello,\nworld."

In languages like Python, it is possible to define a string with a single quote like this:

'this is a valid python string'

However, in Julia, the single quote can only be used for an individual character. If you have more than one, you need to use double quotes:

"This is a valid Julia string"
#vs
'This is NOT a valid string'
