Help using -replace with wildcard characters, specifically braces

Question

Hello all,
Needing help in using -replace with literal wildcard characters, specifically the braces characters. From reading old posts online this seems to have been a notorious shortcoming of PowerShell, but not sure if it's been resolved or not. My simple
code tries to remove the braces as follows (would like to keep the foreach loop and everything as is if possible):
$string = "test[]"
$braces = @("``[","``]")
Foreach($brace in $braces){
If($string -like "*$brace*"){
$string = $string -replace ($brace,"")
write-host $string
This code gives an error at the -replace line, saying "The regular expression pattern `] is not valid." I'm not sure how to pass the literal brace characters to the -replace parameter? Can this be done?

Answer 1

-like is a wildcard operator (it recognized wildcard patterns like * ,? and [a-z].
For a regular expression you use the -match operator.  
Wildcard patterns and regular expressions are not interchangeable.
See:
get-help about_wildcards
get-help about_regular_expressions
for an explanation and examples of each one, and 
get-help about_comparison_operators
for examples of using -like and -match.
