文泉驿是一个开源汉字字体项目
由旅美学者房骞骞（FangQ）
于2004年10月创建
集中力量解决GNU/Linux
高质量中文字体匮乏的状况
目前，文泉驿已经开发并发布了
第一个完整覆盖GB18030汉字
（包含27000多个汉字）
的多规格点阵汉字字型文件
第一个覆盖GBK字符集的
开源矢量字型文件（文泉驿正黑）
并提供了目前包含字符数目最多的
开源字体——GNU Unifont——中
绝大多数中日韩文相关的符号
这些字型文件已经逐渐成为
主流Linux/Unix发行版
中文桌面的首选中文字体
目前Ubuntu、Fedora、Slackware
Magic Linux、CDLinux
使用文泉驿作为默认中文字体
Debian、Gentoo、Mandriva
ArchLinux、Frugalware
则提供了官方源支持
而FreeBSD则在其ports中有提供
所以，今天我们所要分享的就是
文泉驿正黑体
可在Linux/UNIX,Windows
Mac OS和嵌入式操作系统中使用
