I used Lyx (Latex distribution) to convert my content into an HTML page.
I noticed that the sigma character introduced in firefox consists of these two characters: ⎲ ⎳
The first character is for the top of the Sigma character, and the second character is for the bottom. I tried to search Google for these “weird” characters, but couldn't find anything. Do these characters even belong to ASCII? Can someone tell me where I can find these strange characters?
