eudcedit.exe is a font editor built in Windows 2000, XP and Vista, which allows private Unicode characters, which can be easily inserted into any file, to be created.
Private characters are symbols which only work on machine on which they’re installed and correctly allocated. This may be useful if like a company logos or foreign script have to be frequently included into documents, and I expect it is more efficient than adding many images.
eudcedit.exe has minimal tools (a few simple shapes, a pencil, a brush and an eraser!), but it does allow a private character to be created in a fairly simplistic manner.
To use Private Character Editor, go to run and enter ‘eudcedit.exe’. Once it is open, you have to find an empty code point (an unused Unicode character) to use. Then, it is quite self-explanatory. After the character has been saved, to insert it, use Character Map.
Some virus scanners highlight this file as a trojan, but it comes with Windows so that is fairly unlikely.
The University of Heidelberg has a graphical tutorial on eudcedit.exe.
It is definitely worth noting that any characters you make on Private Character Editor will not work on any other computers, but it may still be useful should a symbol frequently be used.
