💡 Best Practices

Do

Serve pages as UTF-8; you can type Ű directly in UTF-8 source
Use &Udblac; in HTML when possible for readability
Use numeric references (Ű or Ű) when escaping is required
Use \0170 in CSS content when generating the symbol via pseudo-elements
Use fonts that support Latin Extended-A characters (U+0100–U+017F)

Don’t

Confuse Ű with Ú (Ú), Û (Û), or Ü (Ü)
Use the old incorrect CSS escape \00170—the correct value is \0170
Put CSS escape \0170 in HTML text nodes
Substitute plain U when the Hungarian letter Ű is required
Double-encode numeric references in dynamically generated HTML
