VS Code 管理人员向缓冲区中输入字符串与对文件系统读取/写入字节块之间的接口。 当 VS Code 保存文件时,它会使用文本编码来确定每个字符变为哪些字节。 有关详细信息,请参阅about_Character_Encoding。 同样,当 PowerShell 运行脚本时,必须将文件中的字节转换为字符以将文件重新构造为 PowerShell 程序。 由于 VS...
虽然字符文本在知道确切的模式时工作,但字符类允许你不太具体。 字符组 [character group]允许一次匹配任意数量的字符,而[^character group]仅匹配组中的字符 NOT。 PowerShell # This expression returns true if the pattern matches big, bog, or bug.'big'-match'b[iou]g' ...
The order of the characters in the array is determined by the ASCII value of the character. For example, the ASCII values ofcandXare 99 and 88, respectively. That range would be presented in reverse order. PowerShell PS>'c'..'X'c b a ` _ ^ ] \ [ Z Y X ...
In order to makeexternal programsuse UTF-8 too, itmustset the console code page(s) - the latter are what well-behaved CLIs consult in order to decide what character encoding to use. A simple solution - both conceptually simple and easy to document - would be to make PowerShell switch to...

We can run through aHere-Stringwith this small loop in PowerShell to examine and view its values. The[byte][char]converts the letter or character to the ASCII number. for($x=0;$x-lt $HexArray[8].Length;$x++){ $Char=$HexArray[8][$x]Write-Host$Char,([byte][char]$Char) ...
It isconverted totext(strings) using the character encoding specified in the$OutputEncodingpreference variable, which defaults to ASCII(!) inWindows PowerShell, and (BOM-less) UTF-8 inPowerShell [Core]. Caveat: If you assign an encodingwith a BOMto$OutputEncoding, PowerShell (as of v7.0) wi...
