Font Obfuscator is an open-source Python library designed to prevent web scraping by obfuscating the character-to-glyph mapping in font files. This tool allows you to shuffle or encrypt character mappings in TrueType Font (TTF) files, making it difficult for web crawlers to extract meaningful text from your website.
- Character Obfuscation: Shuffle or encrypt the character-to-glyph mapping in TTF font files.
- Selective Character Retention: Retain only specific characters in the font file, removing all others.
- Easy Integration: Use as a standalone Python function in your existing projects.

pip install font-obfuscatorHere is an example of how to use the font obfuscation tool to shuffle character mappings in a TTF file:
from font_obfuscator import obfuscator_text
test_text = "这是一段测试文本"
obf_text, obf_io = obfuscator_text(test_text)
print(f"Origin Text: {test_text}")
print(f"Obf Text: {obf_text}")
print(f"Obf Font: {obf_io}")
test_html = """

print(test_html)字体混淆工具是一个开源的 Python 库，旨在通过混淆字体文件中的字符到字形映射，防止网页内容被爬虫轻松提取。该工具允许您在 TrueType Font (TTF) 文件中打乱或加密字符映射，从而增加网站文本的安全性。
- 字符混淆: 打乱或加密 TTF 字体文件中的字符到字形映射。
- 字符集筛选: 只保留字体文件中的指定字符，移除所有其他字符。
- 易于集成: 作为独立的 Python 函数使用，可集成到现有项目中。
