nLab special characters

Special characters

Introduction

This page is to help you copy and paste special characters if you want them. For the moment, it is discouraged to put these in page names, although you may want to use them in redirected pages. It is also usually better to use iTeX when appropriate (mathematical characters outside of wiki links).

Text symbols

Č (more to come!)

Mathematical symbols

These are alphabetical by the LaTeX name. If you don't know the LaTeX name, try Detexify (requires Javascript). Not included are commands like \arccos that produce ASCII, commands like \textbullet that are meant for text mode (use mathmode's \bullet instead), and commands like \Bbbk that produce font and size variants.

Although this is not intended as a list of iTeX commands (since the itex symbols list is pretty comprehensive and well-organised), inevitably people will use it that way too. So please place an asterisk by names that are not recognised by iTeX (which you will discover for yourself when you add it).

Remember to use iTeX itself when appropriate. You mostly will only need to copy and paste these symbols to produce redirects (and most of the time you shouldn't have to come here since the symbol will be on the page already).
