Questions people ask
1Why does 煅 show as a box on some devices?
Not every system ships a font for the CJK Compatibility Ideographs Supplement block. Where none is installed, the character shows as an empty box; adding a font such as Noto fixes it. The character itself is still correct and copies correctly.
