How can I make a customized font based on DeJaVu?

Question

My favorite font is DeJaVu Sans Mono whose style is book. I often cannot tell P (uppercase) from p (lowercase), so I want to make a customized font based on DeJaVu Sans Mono-book.
Note that 0 in DeJaVu Sans Mono-book contains a solid dot.

I want to create a P (p in uppercase) in my format like below.

With fontforge, how do I create my font based on DeJaVu and save the revised font as myfont.ttf?

Answer 1

The process is pretty easy.

1. Open the DejaVu Sans Mono using FontForge
2. Double click on the glyph you want to change
3. Use "Ellipse" tool to create the small dot inside the glyph.
   You can use Shift + drag to create a circle.

4. Use "Pointer" tool to select the circle and position it at the middle of the ellipse of the glyph:

5. Change font name. In order for the changed glyphs to take effect on the new generated, you have to apply a new font name. Go to menu Element ➜ Font Info and change "Fontname", "Family Name" and "Name For Humans" to a different name:

6. Go to menu File ➜ Generate Fonts, select TrueType the path and the filename of the new font:

And you now have your newly created font with the glyphs changed with the dots inside P, p and every other glyph you may apply a dot ellipse:
