问题描述

我需要更改配置文件中的某些值.该文件是没有BOM的UTF-8.我需要以相同的方式保存它.我该如何使用Inno Setup Unicode版?注意:这不起作用，并且此未显示如何正确读取文件.

I need to change some values in a configuration file. The file is UTF-8 without BOM. I need to save it the same way. How do I do it with Inno Setup Unicode edition? Note: This doesn't work, and this doesn't show how to read the file correctly.

推荐答案

const
  CP_UTF8 = 65001;

{ ... }
var
  FileName: string;
  S: string;
begin
  FileName := 'test.txt';
  if not LoadStringFromFileInCP(FileName, S, CP_UTF8) then
  begin
    Log('Error loading the file');
  end
    else
  if StringChangeEx(S, 'žluťoučký kůň', 'ďábelské ódy', True) <= 0 then
  begin
    Log('No value was replaced');
  end
    else
  if not SaveStringToFileInCP(FileName, S, CP_UTF8) then
  begin
    Log('Error writing the file');
  end
    else
  begin
    Log('Replacement successful');
  end;
end;

LoadStringFromFileInCP和SaveStringToFileInCP来自: Inno设置-将字符串数组转换为Unicode并转换回ANSI

LoadStringFromFileInCP and SaveStringToFileInCP come from:
Inno Setup - Convert array of string to Unicode and back to ANSI

代码需要Unicode版本的Inno Setup(Inno Setup 6唯一的版本).
对于Unicode字符串文字，您的.iss文件必须采用带有BOM的UTF-8编码.

The code needs Unicode version of Inno Setup (the only version as of Inno Setup 6).
For Unicode string literals, your .iss file must be in UTF-8 encoding with BOM.
