Question

我有一个带有unicode实体的文本文件。有没有办法通过cmd / batch或cygwin将所有这些实体转换为文本中的等效实体。我似乎无法找到关于此的更多信息。

即journal\u0027s将成为journal's

Answer 1

使用.bat扩展名保存，例如decodeStrings.bat：

0</* :
@echo off

    cscript /nologo /E:jscript "%~f0" %*

exit /b %errorlevel% */0;


    var jsEscapes = {
      'n': '\n',
      'r': '\r',
      't': '\t',
      'f': '\f',
      'v': '\v',
      'b': '\b'
    };


    //string evaluation
    //http://stackoverflow.com/questions/24294265/how-to-re-enable-special-character-sequneces-in-javascript

    function decodeJsEscape(_, hex0, hex1, octal, other) {
      var hex = hex0 || hex1;
      if (hex) { return String.fromCharCode(parseInt(hex, 16)); }
      if (octal) { return String.fromCharCode(parseInt(octal, 8)); }
      return jsEscapes[other] || other;
    }

    function decodeJsString(s) {
      return s.replace(
          // Matches an escape sequence with UTF-16 in group 1, single byte hex in group 2,
          // octal in group 3, and arbitrary other single-character escapes in group 4.
          /\\(?:u([0-9A-Fa-f]{4})|x([0-9A-Fa-f]{2})|([0-3][0-7]{0,2}|[4-7][0-7]?)|(.))/g,
          decodeJsEscape);
    }

    var ARGS = WScript.Arguments;

    for (var i=0;i<ARGS.Length;i++) {
        WScript.Echo(decodeJsString(ARGS(i)));
    }

并使用它：

call decodeStrings.bat  journal\u0027s journal\u0027s

输出：

journal's
journal's

这是一个评估文件的脚本（只需传递尽可能多的文件）：

0</* :
@echo off

    cscript /nologo /E:jscript "%~f0" %*

exit /b %errorlevel% */0;

    var ARGS = WScript.Arguments;

    if (ARGS.Length < 1 ) {
        WScript.Echo("Wrong arguments");
        WScript.Quit(1);
    }

    if (ARGS.Item(0).toLowerCase() == "-help" || ARGS.Item(0).toLowerCase() == "-h") {
        WScript.Echo("Evaluates unicode/special sequences in file");
        WScript.Echo(WScript.ScriptName + " path_to_file [path_to_file]");
        WScript.Quit(0);

    }


    var jsEscapes = {
      'n': '\n',
      'r': '\r',
      't': '\t',
      'f': '\f',
      'v': '\v',
      'b': '\b'
    };

    function decodeJsEscape(_, hex0, hex1, octal, other) {
      var hex = hex0 || hex1;
      if (hex) { return String.fromCharCode(parseInt(hex, 16)); }
      if (octal) { return String.fromCharCode(parseInt(octal, 8)); }
      return jsEscapes[other] || other;
    }

    function decodeJsString(s) {
      return s.replace(
          // Matches an escape sequence with UTF-16 in group 1, single byte hex in group 2,
          // octal in group 3, and arbitrary other single-character escapes in group 4.
          /\\(?:u([0-9A-Fa-f]{4})|x([0-9A-Fa-f]{2})|([0-3][0-7]{0,2}|[4-7][0-7]?)|(.))/g,
          decodeJsEscape);
    }
