Question & Answer :
Chill. Present I demand to usage it successful CSS similar truthful:
nav a:hover {contented:"&darr";}
That evidently gained’t activity since ↓ is an HTML signal. Location appears to beryllium little information astir these “escaped unicode” symbols that are utilized successful css. Location are another symbols similar \2020 that I recovered however nary arrows. What are the arrow codes?
Wherefore don’t you conscionable prevention/service the CSS record arsenic UTF-eight?
nav a:hover:last { contented: "↓"; }
If that’s not bully adequate, and you privation to support it each-ASCII:
nav a:hover:last { contented: "\2193"; }
The broad format for a Unicode quality wrong a drawstring is \000000 to \FFFFFF – a backslash adopted by six hexadecimal digits. You tin permission retired starring zero digits once the Unicode quality is the past quality successful the drawstring oregon once you adhd a abstraction last the Unicode quality. Seat the spec beneath for afloat particulars.
Applicable portion of the CSS2 spec:
3rd, backslash escapes let authors to mention to characters they can’t easy option successful a papers. Successful this lawsuit, the backslash is adopted by astatine about six hexadecimal digits (zero..9A..F), which base for the ISO 10646 ([ISO10646]) quality with that figure, which essential not beryllium zero. (It is undefined successful CSS 2.1 what occurs if a kind expanse does incorporate a quality with Unicode codepoint zero.) If a quality successful the scope [zero-9a-fA-F] follows the hexadecimal figure, the extremity of the figure wants to beryllium made broad. Location are 2 methods to bash that:
- with a abstraction (oregon another achromatic abstraction quality): “\26 B” ("&B"). Successful this lawsuit, person brokers ought to dainty a “CR/LF” brace (U+000D/U+000A) arsenic a azygous achromatic abstraction quality.
- by offering precisely 6 hexadecimal digits: “\000026B” ("&B")
Successful information, these 2 strategies whitethorn beryllium mixed. Lone 1 achromatic abstraction quality is ignored last a hexadecimal flight. Line that this means that a “existent” abstraction last the flight series essential beryllium doubled.
If the figure is extracurricular the scope allowed by Unicode (e.g., “\110000” is supra the most 10FFFF allowed successful actual Unicode), the UA whitethorn regenerate the flight with the “alternative quality” (U+FFFD). If the quality is to beryllium displayed, the UA ought to entertainment a available signal, specified arsenic a “lacking quality” glyph (cf. 15.2, component 5).
- Line: Backslash escapes are ever thought-about to beryllium portion of an identifier oregon a drawstring (i.e., “\7B” is not punctuation, equal although “{” is, and “\32” is allowed astatine the commencement of a people sanction, equal although “2” is not).
The identifier “te\st” is precisely the aforesaid identifier arsenic “trial”.
Blanket database: Unicode Quality ‘DOWNWARDS ARROW’ (U+2193).
