SVS following CJK code points

U+FE00..U+FE02
U+FE0E

EAW is treated as "W" if unassigned (defined by Unicode)

Note

The following result is extracted from https://www.unicode.org/Public/16.0.0/ucd/EastAsianWidth.txt. It is slightly different from https://www.unicode.org/reports/tr11/#Unassigned. U+2FFFE, U+2FFFF, U+3FFFE, and U+3FFFF are missing, but they are "Noncharacter", not "Unassigned" (or "Reserved"). This shows that we do not have to care about whether they are included in the list of CJK code points or not. To simplify the ranges, U+2FFFE and U+2FFFF are merged to U+20000–U+2FFFD here.

U+3400..U+4DBF (㐀..䶿)
U+4E00..U+9FFF (一..鿿)
U+F900..U+FAFF (豈..﫿)
U+20000..U+3FFFD (𠀀..𿿽)
