The glyph is not a composition . Its width in East Asian texts is determined by its context . It can be displayed wide or narrow. In bidirectional text it acts as Other Neutral . When changing direction it is not mirrored . If its East Asian Width is “narrow”, U+FFFD forms a word with similar characters, which prevents a line break inside it. Otherwise it allows line breaks around it, except in some numeric contexts.
