fdirectly in body content; use entities only when necessary - Serve pages as UTF-8 so Basic Latin characters render without entities
- Use numeric references (
forf) when escaping is required - Use
\66in CSScontentwhen generating the letter via pseudo-elements - Remember lowercase f is U+0066 and uppercase F is U+0046 when case matters
Don’t
- Overuse numeric entities for
fin normal readable text - Expect a named HTML entity like
&f;—none exists for this letter - Confuse plain
f(U+0066) with ƒ (f hook / florin, U+0192,ƒ) - Put CSS escape
\66in HTML text nodes - Mix entity styles randomly in one file without reason
