项目概述
这个工具是一个用于分析和可视化字体文件中包含的 Unicode 字符的实用程序能够扫描指定字体文件提取其中包含的所有 Unicode 字符并按 Unicode 区块分类生成 PDF 文档直观展示字体支持的所有字符。
核心功能
字体扫描自动扫描系统字体目录识别 TrueType (.ttf) 和 OpenType (.otf) 字体文件字符提取使用 FreeType 库提取字体中支持的所有 Unicode 字符区块分类按照 Unicode 标准区块对字符进行分类PDF 生成使用 Haru PDF 库生成包含所有字符的可视化文档智能排版自动处理多页文档、分栏显示和换行
主要组件
1. UnicodeBlock 结构体
定义 Unicode 区块的起始码点、结束码点和名称包含完整的 Unicode 15.0 标准区块定义。
2. FontUtils 类
封装 FreeType 库操作提供以下功能
初始化 FreeType 库从字体文件提取 Unicode 字符集Unicode 码点到 UTF-8 编码的转换按 Unicode 区块过滤字符
3. PDFDocument 类
封装 Haru PDF 库操作提供以下功能
PDF 文档初始化字体加载和编码设置字符页面生成支持多页彩色标题和统计信息添加文档保存
4. FontScanner 类
负责扫描字体目录提供以下功能
递归扫描指定目录中的字体文件按扩展名和文件名模式过滤字体支持排除特定样式的字体如粗体、斜体等
技术特点
跨平台支持使用标准 C17 和跨平台库完整 Unicode 支持覆盖所有 Unicode 15.0 标准区块高效处理智能分页和区块分割避免内存问题美观输出彩色渐变标题、清晰的字符网格布局灵活配置可调整的页面布局参数边距、字体大小等
使用示例
int main() {try {FontUtils font_utils;fs::path font_dir C:/Windows/Fonts; // 字体目录fs::path output_dir output_pdfs; // 输出目录FontScanner scanner(font_dir);auto font_files scanner.GetTTfFont(); // 获取常规字体文件for (const auto path : font_files) {std::cout 处理字体文件: path std::endl;PDFDocument doc(path, output_dir);doc.GenerateWithUnicodeChars(font_utils);doc.Save();}}catch (const std::exception ex) {std::cerr 错误: ex.what() std::endl;return 1;}return 0;
}依赖库
FreeType用于字体解析和字符提取Haru PDF用于 PDF 文档生成C17 标准库文件系统、字符串处理等STL容器、算法等
输出示例
生成的 PDF 文档包含
彩色渐变字体标题字体统计信息总字符数按 Unicode 区块组织的字符网格自动分页的多页文档
应用场景
字体设计师验证字体覆盖范围开发人员检查字体对特定语言的支持多语言项目中的字体兼容性测试字体文档自动生成学术研究中的字符集分析
扩展性
项目可轻松扩展以支持
自定义 Unicode 范围过滤额外的输出格式如 HTML、CSV字符属性显示如编码点、名称字体特性分析如连字、变体
