I just need some piece of software to quickly open a font file and check what's inside. Requirements:

  1. Ability to open a font file.
  2. Having a standalone portable version (usually, it's just a .zip archive instead of setup.exe installer) which will never need administrative rights to run. It also means that .NET/Java applications are not acceptable.
  3. Open-source/free.

I forgot to clarify a few things.

Firstly, I need to define what I mean by "font viewer". It is not the application that shows me a portion of text typed in the selected font, it is the application with the interface similar to BabelMap. The reason of my dissatisfaction with BabelMap is that it's not a font viewer, it's a character map which shows me the entire Unicode grid, but... what should I do with such a grid? Suppose I open a font that contains only 100 glyphs. What will I see? A giant Unicode grid with many thousands of empty cells and a small amount of cells showing how its corresponding char looks in the font??? This type of interface seems totally useless for me. I expect to see a grid with all glyphs contained in the font, but without glyphs not supported by the font, and without empty (unused) cells.

Secondly, I need to note that the application should not be limited to installed fonts (that is, located in "Windows/Fonts" directory)! I need to open a font file which may be located in any directory, without having to "install" the font. The application should provide something like a standard "File > Open" dialogue box, and allow me to select any font file.

NexusFont has a portable version available for Windows. It was written by JungHoon Noh. It allows you to view and compare font files. It is completely free.

I have used it extensively, and I can recommend it.

I've used two Font Viewers that are portable, open source, gratis, will show fonts in other folders, and will display all characters in the font package but not in a grid. You can download and try them, if you wish.

1 - my preferred viewer - http://us.fontviewer.de/Download/

2 - http://www.ampsoft.net/utilities/FontViewer.php

Hope these will help!

  • It looks like dp4 (fontviewer.de) will meet the querent's needs. Commented Sep 6, 2019 at 13:58
