PowerShell: Create a char array from a string

In PowerShell, a string can be converted to a character array with the following simple construct:

PS C:\> [char[]] 'abcde'
a
b
c
d
e

Alternatively, the string's ToChararray() can be used:

PS C:\> 'abcde'.ToCharArray()

Lastly, the -split operator can be used together with a positive look-behind and look-ahead regular expression assertion.

However, it should be noted that this operation splits the string into an array of strings, not of characters.

PS C:\> 'abcde' -split '(?<=.)(?=.)'
