找出字体支持的字符 [英] Finding out what characters a font supports

问题描述

如何在Linux上从TrueType或嵌入的OpenType字体中提取受支持的Unicode字符列表？

How do I extract the list of supported Unicode characters from a TrueType or embedded OpenType font on Linux?

是否有可用于处理的工具或库一个.ttf或一个.eot文件，并建立一个由字体提供的代码点（如U + 0123，U + 1234等）列表？

Is there a tool or a library I can use to process a .ttf or a .eot file and build a list of code points (like U+0123, U+1234, etc.) provided by the font?

推荐答案

这是一个使用 FontTools 模块的方法（您可以安装类似于 pip install fonttools ）：

Here is a method using the FontTools module (which you can install with something like pip install fonttools):

#!/usr/bin/env python
from itertools import chain
import sys

from fontTools.ttLib import TTFont
from fontTools.unicode import Unicode

ttf = TTFont(sys.argv[1], 0, verbose=0, allowVID=0,
                ignoreDecompileErrors=True,
                fontNumber=-1)

chars = chain.from_iterable([y + (Unicode[y[0]],) for y in x.cmap.items()] for x in ttf["cmap"].tables)
print(list(chars))

# Use this for just checking if the font contains the codepoint given as
# second argument:
#char = int(sys.argv[2], 0)
#print(Unicode[char])
#print(char in (x[0] for x in chars))

ttf.close()

脚本以字体路径作为参数：

The script takes as argument the font path :

python checkfont.py /path/to/font.ttf
