Dev-C++中文乱码终极解决方案：全链路UTF-8配置指南字符编码是计算机处理文本信息的基础，它定义了字符与二进制数据之间的映射规则。在Windows平台的C/C++开发中，由于历史原因，系统默认的GBK编码与现代通用的UTF-8编码并存，导致编码错位问题频发。其核心原理在于源代码文件编码、编译器解释编码和终端显示编码三个环节的不匹配。解决编码问题的技术价值在于确保程序内外部数据表示的一致性，避免乱码，提升代码的可移植性和可维护性。在应用场景上，尤其在使用Dev-C++等传统IDE进行中文字符串输出、文件读写时，编码配置至关重要。本文聚焦于通过配置编辑器、编译器参阅读详情

Onescript.cpp:
#define GOSSIP_TEXT_TAVERN GB2312ToUTF_8(" 【主菜单】")

以上代码可以WIN下用也可以在LINUX下用
可是编译出错:
Onescript.cpp.cpp(358) : error C2660: “GB2312ToUTF_8”: 函数不接受 1 个参数
主要是我不懂C++,请教高人给修改修改!
