I want to write: ⃗E, I tried to C-x 8 <RET> COMBINING RIGHT ARROW ABOVE <RET> E it is displaying in Emacs like:

how Emacs displays ⃗E

I want to use Unicode (without Tex).

EDIT

in reply to Drew's comment:

What I want is to put the arrow above the letter something like this:

What I want to write

It appears in my browser correctly.

Yes, sure I can move the cursor past the arrow but before the E.

doing C-u C-x = for the first character gives:

             position: 45 of 49 (90%), column: 2
            character: ⃗ (displayed as ⃗) (codepoint 8407, #o20327, #x20d7)

And the next character (letter E) output is:

             to input: type "C-x 8 RET 45" or "C-x 8 RET LATIN CAPITAL LETTER E"

  • 1. It's not clear what is different between what you wanted to happen and what happened. Please clarify/elaborate. 2. What happens if you put the cursor just before the character(s) you get and you use C-u C-x =? What does Emacs tell you then about what that character is? 3. Can you move your cursor past the arrow but before the E? That would indicate that there are two characters present. If so, put your cursor there and do C-u C-x =. Try to provide as much info as you can about just what you want and what you get instead. – Drew Dec 26 '17 at 21:46

Combining characters always combine with the character that comes before them, so put the E first. Note that in the output of C-u C-x = you pasted above, the arrow has combined with the space character that came before it.

  • If I type E C-x 8 <RET> COMBINING RIGHT ARROW ABOVE <RET> the arrow doesn't appear above the letter. – Ahmed Elsawy Dec 27 '17 at 19:53
  • However, I found out that typing C-x 8 <RET> VECTOR OR CROSS PRODUCT <RET> C-x 8 <RET> COMBINING RIGHT ARROW ABOVE <RET> displays a cross product with a right arrow above it (as I wanted for letter E). – Ahmed Elsawy Dec 27 '17 at 19:59
