Hello
Unfortunately, Alt+234 does not produce Omega on Windows because it uses a Unicode table instead of ASCII.
You can open Character Map in the Start Menu, Windows Accessories.
To visually see all characters and their "unicode" codes
The curious code for Omega is U+03A9 (4th page)


Checking the "Advanced View" box gives you options like "Windows Greek" which limits the display; you can select and then copy, a bit cumbersome...

Cheers
If the answer helped you, a little thumbs up is awesome... Solved is perfect.

Let him who has never opened a user manual throw the first mouse at me ;-)

Hello
To go to the very end
There is a little software UnicodeInput created by John Cook.
See you later

Hello Macintoch,

The Emoji menu is the shortcut Windows + ;
(hold down the Windows key and press the semicolon key)

It's in the language symbol ohmega with Windows 11


Ὠ

Or with ==► LaTeX - Character table

Good evening,

alt + 234 = Û

for the symbol Ω, the best way is to copy/paste into a new file (right-click anywhere on the desktop) and choose Notepad, for example

don't forget to save the Notepad file as Omega, for example or Omega letter

after that, all you have to do is "copy/paste"

Ω Ω

otherwise, I looked and searched, I can't find a solution; maybe download a font that would contain the Omega symbol.
