Top Forums Shell Programming and Scripting How to type the Omega symbol Ω in unix shell script Post 302195602 by era on Thursday 15th of May 2008 12:23:29 PM

It depends entirely on what character set it's in. Are you using Unicode or some legacy encoding? In any event, there is no firm standard for how to enter extended symbols; find a program which allows you to pick it from a menu, or simply copy-paste it from here.

If you know the raw character code, any decent editor will probably offer an input method for entering the character code in hex or something.

The fact that you were able to enter that character here would indicate that you already have some way of typing this character.

The Unicode code point for Omega is U+03A9; there is also a separate "ohm symbol" at U+2126
