I have hundred of TTF font files and I just want to test them without having to install. Is there any text editor in Windows that allows to do so?
I do not know such editor, but you can try some of these utilities: http://www.portablefreeware.com/forums/viewtopic.php?f=4&t=1162
at least some of them can view fonts which are not installed and use custom text to compare them. I have also some older util for this, but I am not able to remember its name now.
