Hi all

I'm having a new issue with this font:
http://radagast.ca/snellen/snellen-font.zip

When I convert an SVG file to PNG or PDF using rsvg-convert (librsvg),
I see a box with 0020 instead of the space. This does not happen when I
use other fonts.
OTOH the SVG always looks fine.

I'm having problems with sending attachments right now, so I've
uploaded the files here:
https://we.tl/tZQRrsyqnJ

The command to convert to PDF is:

rsvg-convert test.svg -f pdf -o test.pdf

Thanks in advance
Federico

Could it be because the space character is not defined in that font?

When I open the SFD in Fontforge I can see that the space character at 0x020 is X’ed out, as are all the characters except the alphabetics.

How can I define the space character in FontForge?

I googled but couldn't find anything.
I also tried entering U+0020 within the 0x20 cell of a new (forked)
Snellen.sfd file, but I cannot make it work.

Obviously I don't have any background in typography.
I need some good links to go further.

Thanks
Federico

If you need a space, can you use a space from another font? That would be the easy way out.

Otherwise, there is a link to "Design With FontForge” at https://fontforge.github.io/en-US/
and another "Design With FontForge” at https://www.gitbook.com/book/yellowxz/designwithfontforge/details
to get you started with FontForge.

I don’t want to try to teach anybody how to use FontForge.

The space's Unicode number is u+0020, so that much is correct. To define a
space glyph, you just have to assign it a width.

Select the space from the grid in the font view window. Then select Set
Width in from the Metrics menu. Enter a value in the Set Width To line of
the dialog window. The value doesn't matter but should, for design
purposes, be around the average width of a lowercase letter or a bit
narrower. You can adjust this later, of course.

Thank you Jason! This worked.
I'll try studying FontForge in September...
