It must have just been one of those glitches, all seems normal my end except still not being able to log out and despite many requests it still seems beyond the technical capabilities to make an ohms available. :(WhΩse capabilities?It is possible but I think it depends how your keyboard layout is arranged.
In MS Word, use insert tab, then symbol, then select appropriate symbol …. Ω, then copy, then paste into here. Seems a long way round but the ALT codes are not recognised by my keyboard setup...

It seems that nobody has described the use of the Microsoft Character Map for this purpose. The Insert | Symbol command in Word produces quite a number of symbols but the Character Map is much more extensive and works in virtually any Windows application, not just Word.
The Character Map is found in all recent versions of Windows. In Windows 10 it is invoked under Start | Windows Accessories, or you can just search for it by right-clicking Start (Windows symbol) then selecting Run and entering its name. I use it a lot so I have created a short cut on my task bar.
The grid shows all the regular alphabetic and numeric characters, punctuation marks, then goes on to common accentuated versions of letters. Then follows a whole slew of Greek, Cyrillic and Arabic characters.
You select a character from the grid. You then click the SELECT button and it shows below. Then click the COPY button to copy it to the clipboard. You then go the text where you want to insert it and select Paste, or CTRL + V.
When a character is selected, a number shows bottom left following "U +". This is the Unicode for the character expressed in hexadecimal. On the right shows the corresponding fast key-stroke. This is done by holding down the ALT key and keying in the four-digit decimal equivalent of the Unicode on the right numerical keypad. In the first example I have shown, I have selected a proper, mid-height decimal point. The Unicode is 00B7 and the decimal equivalent is 0183. It is also possible to produce this same symbol by holding down the ALT key and keying in the three-digit decimal equivalent of the extended 8-bit ASCII code, in this case 250.
To produce a capital Omega, you need to scroll down a bit further to find and select it, then click on COPY, then SELECT and go to the text and enter CTRL + V. As Legh says, there is no key-code available here - because the Unicode value in decimal would be too large for four digits.
Examples of use.
Characteristic impedance 75 Ω
π = 3·1416
If you want more fun with the Character Map, select the Advanced View box. However this is well beyond where I want to go.
It is odd that the "Insert Special Character" button on this forum front end message compose box produces only a limited number of characters, not even the Omega symbol used to illustrate the button.
The usage of HTML and XML directives to produce these characters, as some have demonstrated, seems to me to bit like using a steamroller to crack a nut - unless you are seriously involved with web page design or the like.
