whitespace html entity?

is there a corresponding html entit开发者_运维问答y that represents a whitespace and like this '|_|'??

I think you're looking for a non-breaking space.

 

---

Also note   as the entity for space rather than   for non-breaking space.

---

if you mean "␣", it's ␣ ( = ␣ )

---

update: above is "open box" character. more accurate symbol might be "shelf" symbol ˽ ˽

---

update 2: there is yet another character, counterbore ⌴ ⌴, but it's rather a technical graphical symbol.

please note, the you can have some problems with the second symbol "shelf", because it is a modifier symbol.

i'd choose the "open box" ␣

Non-breaking space.
