Problem scenarios

Attribute values of non-ASCII characters are often used when writing styles, as follows:

?

1234567891011

.hot_list .sign_discount:before {    content: "Full reduction";    padding: 0 8px;    margin-right: 7px;    font-size: 12px;    line-height: 14px;    color: #fff;    text-align: center;        border-radius: 11px;}

However, garbled characters may sometimes appear in Chrome:

In addition to content, font fonts are also frequently used for non-ASCII characters, such as font-family: ""

Best practices

To avoid the above Encoding Problems, we recommend that you use backslash escape when non-ASCII characters are involved in CSS to avoid Encoding Problems:

backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear.

See http://www.w3.org/TR/CSS2/syndata.html#escaped-characters for details

Therefore, the preceding example can be changed:

?

1234567891011

.hot_list .sign_discount:before {    content: "\6ee1\51cf";    padding: 0 8px;    margin-right: 7px;    font-size: 12px;    line-height: 14px;    color: #fff;    text-align: center;        border-radius: 11px;}
