- A fallback font is a reserve typeface containing symbols for as many Unicode characters as possible. When a display system encounters a character that is not part of the repertoire of any of the other available fonts, a symbol from a fallback font is used instead. Typically, a fallback font will contain symbols representative of the various types of Unicode characters. Systems that do not offer a fallback font typically display black or white rectangles, question marks, the Unicode Replacement Character (U+FFFD), or nothing at all, in place of missing characters. Placing one or more fallback fonts at the end of a list of preferred fonts ensures that there are no missing characters. (en)
- 後備字體（Fallback font）是指在當時顯示的字型缺乏某些字元時，被用於顯示缺失字元的字體。因為其作為顯示的最後一道防線，後備字體應該盡可能包含所有Unicode字元。 當缺失字元沒有後備字體用於顯示時，通常會將缺失字元改為黑色方塊、白色空心方塊、問號、Unicode佔位字元(U+FFFD)顯示，或者乾脆略過該字元。在實務上，像是CSS等支援字體列表依序顯示的系統，通常會將一或多套後備字體置入列表最後，以防止缺字的情況發生。 (zh)
