[SOLVED] Synedit shows ⋅ as a quadrangle

[CM630]

When I execute the following code SynEdit displays the dot as a quadrangle.
TEdit, on the other hand, displays it as it should.
Both controls have the font CourierNew. Can I do something to have the ⋅ character displayed?

Code: Pascal  [Select][+][-]

1.   Edit1.Text := '2⋅0,95 = 1,9';
2.   SynEdit1.Text := '2⋅0,95 = 1,9';

That happens on Win 10 64 bit with Lazarus 3.0.

It's not the Font. It's probably the encoding.

What Unicode character is that?
Alt+250 dot seems to be fine.

I have no idea what is “Alt+250”.
Maybe the image will answer the question about the Unicode character.

Alt+250 is Unicode character "middle dot"/

You can get it by holding the Alt key and pressing 2 5 0 on your numeric keyboard.
It looks the same as your "Dot operator" character (which seems to be char($22C5)).

I can't even copy and paste that character in my code editor of Lazarus (in the source).
Even copying it in Notepad++ (in UTF8 mode) doesn't work.

Does loading it from a file work?
(then it might be a conversion problem from source-code to program-code.)

Edit: O, it just occured to me.... That character might not even be in the Courier New font.
Did you try another font??

Note: TEdit/Windows substitutes fonts automatically when characters are not supported.
In this case Windows substitutes it for "Cambria Math".

Edit #2: Yes... this works fine:

Code: Pascal  [Select][+][-]

1.   SynEdit1.Font.Name := 'Cambria Math';
2.   Edit1.Text := '2' + #$E2#$8B#$85 + '0,95 = 1,9';
3.   SynEdit1.Text := Edit1.Text;

(although Cambria Math doesn't look good in SynEdit but that's another matter...)

Thanks, it shows fine.

Indeed, I will use that char instead.

I can't even copy and paste that character in my code editor of Lazarus (in the source).

I can neither.

No, I have it in the keyboard layout, so I just type it.

That sounds like a perfectly reasonable explanation. So I will use the other dot ·

Thanks!


Edit: The dot char seems to be #8901.
