Wondering if a given character sequence can be used as an unquoted font family name in CSS? Read all about it, or just use this tool.
You can use this as an unquoted font family name in CSS:
font-family: Hawaii\ 5-0;
Standard CSS character escape sequences for supplementary Unicode characters aren’t currently supported in WebKit, though. It’s better to leave these characters unescaped.
You can use it with quotes:
font-family: 'Hawaii 5-0';
If used unquoted, this font-family name contains a keyword in CSS, and it refers to the keyword value rather than a font family with that name. If you mean to use a font with this name rather than the keyword value, you must use quotes:
font-family: 'sans-serif';
