Yes, it is now losing the monospace characteristic and it's a good feature to add!
I can't promise that I will have time for it in the next days.

Would somebody like to contribute in it?

Got a small ruby program, generating 1-bpp font from .hex

It's great!
We can use it until this feature isn't implemented in the "original" font converter.

monospace font realy actual

from lv_utils.

The hex2lvfont.rb converter only deal with font in hex format [1].
The two fonts I know that are defined this way are:

• GNU unifont : http://unifoundry.com/unifont.html
• Unscii : http://pelulamu.net/unscii/

I updated the font converter with monospace feature.
If you tested it and have any remarks please open a new issue for it.

Based on the suggestion here: lvgl/lvgl#229
I modified the monospace support to leave letters "slim" (not extra columns to not occupy extra space) and updated drawing algorithm of the library align letters during rendering. The updates are in lvgl/dev-5.2 branch.
