At w3schools has the reference of all the characters - special, symbols, alphanumeric. I did not understand the purpose of having this representation of the characters. In the example below the output is the same, it only changes the entity.

When should we use CSS entity and / or when to use the character?

Is there a difference between writing one way or another?

.copy1:before{content:'<div class="copy1"></div>
<div class="copy2"></div>
<div class="copy3"></div>
<div class="copy4"></div>A9'; margin-right:3px}
.copy2:before{content:'©'; margin-right:3px}
.copy3:before{content:'.copy1:before{content:'<div class="copy1"></div>
<div class="copy2"></div>
<div class="copy3"></div>
<div class="copy4"></div>A9'; margin-right:3px}
.copy2:before{content:'©'; margin-right:3px}
.copy3:before{content:'%pre%41'; margin-right:3px}
.copy4:before{content:'A'; margin-right:3px}A9 => ©
©     => ©

%pre%41 => A
A     => A
41'; margin-right:3px}
.copy4:before{content:'A'; margin-right:3px}A9 => ©
©     => ©

%pre%41 => A
A     => A

%pre% %pre%

w3schools seems to have invented this name "css entities", inspired by html entities . This is a list of code points unicode, which can be used "escaped" with \ . But you can also use the character directly as you have shown. The current spec says what this is worth:

So it's okay to use unicode characters directly as a value of content , as long as your file is saved and served with correct encoding - in UTF-8 case, but characters in other encodings also work if everything is being saved and served correctly.
