理论上适用于任何字体。

 

实际上测试，有的字体设计内部存在bug, 调用不成功。 个人blog成功案例

 

一： 下载安装 FontForge

Windows, Mac and GNU+Linux.

 

二 Python 脚本

minify.py 文件

import glob
import re
import fontforge


extensions = [".html", ".js"]
pattern = re.compile("(fa-[-\w]+)")


# 获取使用到的图标
def get_used_icons(path):
    icon_dict = {}
    for filename in glob.glob(path, recursive=True):
        for extension in extensions:
            if extension in filename:
                for line in open(filename, encoding='utf-8'):
                    for match in re.finditer(pattern, line):
                        icon_dict[match.group()[3:]] = True
    return icon_dict


# 去除除了传入的字典的图标
def minify(path, used_dict):
    font = fontforge.open(path)
    assert isinstance(font, fontforge.font)
    selection = font.selection
    assert isinstance(selection, fontforge.selection)
    selection.all()
    for i in selection.byGlyphs:
        assert isinstance(i, fontforge.glyph)
        if i.glyphname not in used_dict:
            font.removeGlyph(i)
    font.generate(path)


if __name__ == '__main__':
    web_path = "V:/hexo/blog/public/**"
    font_path = "V:/hexo/blog/themes/matery/source/libs/awesome/webfonts/"
    font_list = ["fa-brands-400.woff2", "fa-regular-400.woff2", "fa-solid-900.woff2"]
    used_icon_dict = get_used_icons(web_path)
    for font_name in font_list:
        minify(font_path + font_name, used_icon_dict)

三： 运行压缩脚本

D:\Program Files (x86)\FontForgeBuilds>bin\ffpython.exe d:\Work\Dev\minifyFont\minify.py

 

压缩结果 可以看到 字体 https://blog.17lai.site/libs/awesome/webfonts/fa-brands-400.woff2 压缩到个位数KB, 原大小100多KB!

 

四： 字体 css 压缩 

 

下面是另一个 css 压缩脚本，调试运行还有问题，谁有空debug 调试一下？

miniCSS.py
