If you use Windows, there's a utility that comes with it, called "Character Map", which shows the ALT or CTRL + xxxx keystroke combinations for characters on all the resident fonts loaded into Windows [all the fonts you can use without a 2nd party manager].
Typically, this is around 75 or more local fonts.
But if you are preparing a post for this forum, select your special characters from the Verdana (or Arial) font only.
