As with in the self-answer, I like to be able to remove control characters from text to get a single line string.
Does there exists a PowerShell Escape function for Special PowerShell Characters?
(Similar to the Regex.Escape(String) Method for escaping special regex characters)
Or is there a smarter way to do this than the self-answer?
(I am less concerned with the Unicode escape sequence: `u{x}
)
Using a 正则表达式回调:
$Backtick = @{}
foreach ($Char in '0abefnrtv`'.ToCharArray()) {
$Backtick[$ExecutionContext.InvokeCommand.ExpandString("``$Char")] = "``$Char"
}
$SpecialCharacters = '[' + (-Join $Backtick.get_Keys()) + ']'
function Escape($Text) {
[regex]::Replace($Text, $SpecialCharacters, { param($Match) $Backtick[$Match.Value] })
}
Escape 'Test
123'
Test`n123
