I wana remove one entity from popup list in HTML documents.
the popup is populated with these:

&nbsp
 
≎̸
≏̸

as you see the entity is &nbsp (first entity) is not correct because ";" is missing at the end.
every time i try to add   entity to HTML document this popup is populated with wrong option (first one) and I'm frustrated of this.
i wana remove this entity from popup list.
how to do this?

from HTML 5.0 perspectives, semicolon is not required for this entity. Both variants are correct.

If you want to remove it, create phped-<yourname>.rel in %AppData%\NuSphere\PhpED\config with the following content:

[HTML.special.HTML50]
000160.B=

that's it.

thank you
