How do I encode Unicode character codes in a PowerShell string literal?

by

Replace ‘\u’ with ‘0x’ and cast it to System.Char:

PS > [char]0x0048
H

You can also use the “$()” syntax to embed a Unicode character into a string:

PS > "Acme$([char]0x2122) Company"
AcmeT Company

Where T is PowerShell’s representation of the character for non-registered trademarks.

Note: this method works only for characters in Plane 0, the BMP (Basic Multilingual Plane), chars < U+10000.
