如何从字体文件中删除字符? [英] how to remove characters from a font file?

问题描述

我已经下载了 DejaVu开源字体，并希望将其用作WebFont，但是即使将其转换，我得到一个大文件，并且因为我将使用的网站只有几种语言(阿拉伯语，法语，amazigh)，所以我不需要一些字符.

i've downloaded the DejaVu open source font and want to use it ad a WebFont, but even when converting it, i get a large file, and because the website i'll use will be only in few languages (arabic, french, amazigh) then, i dont need some characters.

有没有办法浏览字体文件并删除不需要的Unicode字符范围?

so is there a way to browse the font file and delete the unnecessary range of unicode characters that i'll not need?

推荐答案

我找到的最简单的方法是使用pyftsubset工具="noreferrer">字体工具.这是一个示例:

The easiest method I found is to use pyftsubset tool from FontTools. Here's an example:

$ pyftsubset NotoSans-Regular.ttf \
      --unicodes=U+0400-045F,U+0490-0491,U+04B0-04B1,U+2116 \
      --output-file=NotoSans-Regular.cyrillic.woff2 \
      --flavor=woff2

注意:woff2输出需要 Brotli .

我围绕它编写了一个简单的脚本，该脚本可自动执行整个过程，包括在分割字体文件后生成CSS文件.您可以在这里找到它: https://github.com/johncf/ttf2web
