unicode-range
CSS unicode-range Property
The Unicode-range descriptor defines the specific range of the characters that are used with fonts specified by the @font-face property for the use on the page. When @font-face is not supported, a fallback font should be included.
If the page does not use a character in the range, the font is not downloaded. If at least one character is used, the whole font is downloaded.
Unicode points are preceded by a U+ followed by up to six characters that make up the character code. Points or ranges that do not have this format are considered invalid and will make the property be ignored.
There are a lot of Unicode options to use. Basic Latin (0020—007F) is the most common range for English sites.
