Font "FandolSong-Regular" does not contain requested (fontspec) Script "CJK".

Using \overbracket and \underbracket from (unicode-math) mathtools' package. (unicode-math) (unicode-math) Use \Uoverbracket and \Uunderbracket for (unicode-math) originalunicode-math' definition.

I'm going to overwrite the following commands (unicode-math) from the `mathtools' package: (unicode-math)
(unicode-math) \dblcolon, \coloneqq, \Coloneqq, \eqqcolon. (unicode-math)
(unicode-math)
(unicode-math) Note that since I won't overwrite the other (unicode-math) colon-like commands, using them will lead to (unicode-math) inconsistencies.

Font "FandolFang-Regular" does not contain requested (fontspec) Script "CJK".

Font "FandolKai-Regular" does not contain requested (fontspec) Script "CJK".

Font "FandolHei-Regular" does not contain requested (fontspec) Script "CJK".
