Your unicode omega character looks okay to me.
But the emoji character at the end of the emoji list in the edit window does not. ![Ohms \$\Omega\$](https://www.eevblog.com/forum/Smileys/default/omega.gif)
How did you type the omega character?
Your omega in the quoted text above, indeed appears in inverted colors in a dark theme. For the unicode capital omega, usually I just google "unicode ohm", then copy paste the character from that web page into the EEVblog message.
https://www.fileformat.info/info/unicode/char/2126/index.htm Same page shows how to write an omega when writing code, but I just copy pasted the graphic symbol.
To type it from the keyboard, one need to remember the unicode code for capital omega, which is "2126". Then,
- in Windows, ALT+2126 (keep ALT key pressed while typing the digits 2 1 2 6 from the numerical keypad, then release the ALT key). The digits must be typed from the numerical keypad, not from the first row, i.e. for "1" you press the key "1/End", and not the key "!/1".
- in Linux, pres CTRL+SHIFT+u, release it, then 2126 (keypad or not, doesn't matter), then ENTER.
This forum also supports LaTeX, so apart from the Unicode ohm Ω and the emoticon ohm
![Ohms \$\Omega\$](https://www.eevblog.com/forum/Smileys/default/omega.gif)
, there is yet another way to write capital omega in LaTeX as "\Omega" \$ \Omega\$. Note that the LaTeX won't be rendered when preview, but will appear correct when the message is posted.
Another tricky thing is that the spelling of a LaTeX ohm, which is "backslash dollar backslash Omega backslash dollar", is the same as the Emoticon ohm, and the emoticon seems to take precedence over LaTeX here, so put an extra space or something else in the LaTeX spelling to force the LaTeX over Emoticon.
For the black theme, LaTeX ohm appears fine, Emoticon ohm have a wrong white background.
Also it might work to write ohm as an embedded png rendered somewhere else, trying this for the first time:
![](https://latex.codecogs.com/png.latex?\sum^{i%3D\infty}_{i%3D0}\omega\Omega_{i})
Yep, works, but this one appears too on a white background on the dark theme.
Same, but rendered by EEVblog: \$\sum^{i=\infty}_{i=0}\omega\Omega_{i}\$
This last one appears correctly (dark background) on the dark theme, yet a singe capital omega in latex, rendered by EEVblog, will have white background because it will be interpreted as the emoticon ohm.
For EEVblog rendered LaTeX, it doesn't show to preview, and needs a page refresh after posting it, in order to re-render any later edits.
To recap:
Ω - Unicode ohm
![Ohms \$\Omega\$](https://www.eevblog.com/forum/Smileys/default/omega.gif)
- Emoticon ohm
\$\Omega \$ - LaTeX ohm (from EEVblog)
![](https://latex.codecogs.com/png.latex?\Omega)
- LaTeX ohm (as a png from another site, codecogs)
- typed from the keyboard (Windows)
ALT+2126
- typed from the keyboard (Linux)
CTRL+SHIFT+u 2126 Enter
- as emoticon (seems to be the same as embedding LaTeX notation, IDK)
\$\Omega\$
- as LaTeX, but this is the same as Emoticon
\$\Omega\$
- as LaTeX, with an extra space added in order to distinguish it from the Emoticon, thus enforcing a LaTeX rendering, and not the Emoticon gif
\$ \Omega\$
- as a LaTeX PNG image rendered by a 3rd party
