If you want to enter accented characters in eDocBuilder, either when customizing a template or setting up a template for customization, the quickest approach is to use Windows ALT key codes to get the character that you want to show.
Hold down the ALT key on the keyboard, type the code for the character on the number pad, and release the ALT key.
Depending on the operating system version, and the keyboard input configuration, there can be other methods of entering alternative characters. The font needs to support Western input and include the accented characters you want to type.
A few common accented character codes are shown below, for your reference.
