Not all fonts are suitable, but cannot be determined in the preview

[Paddy Landau]

Enhancement request:

When setting the fonts in Grub Customizer, the preview does not indicate if the special characters (lines, corners and arrows) will display correctly.

Please would you add to the preview a section of the lines and corners, and the up- and down-arrows.

I am attaching a screen-shot to show the two areas to which I am referring.

This would help to determine whether or not the font is suitable.

Thank you.

Also it would be great if someone could provide a list of suitable fonts. It would save us hours of try+reboot iterations.

Amine: That is a great idea! I have stuck with the default, as I have not yet found even a single font that is suitable :(

I also cannot find a font that shows the text-graphics box or the arrows. Nor do my font color choices affect the grub display.

If it matters, during the build/install I was asked what display manager I use, and I chose mdm. My OS is Linux Mint Debian, UP6, with Mate and kernel Linux 3.2.0-4-amd64.

There were some problems regarding fonts. I fixed a problem in 4.0. Now all fonts should work. However the broken borders are still present on most font because most of them doesn't containt the required chars. A font that definitely works is Deja Vu Sans Mono.

@Daniel, thank you for your efforts. I shall try this out when I have a little time.

[Daniel Richter (danielrichter2007)]

No futher answer. I think this is fixed, so I set this bug to status fixed.

[Paddy Landau (paddy-landau)]

I've just tested the new version, which came in today. It still does not show the lines on the preview.

This means, as @nh2amine says, plenty of time wasted setting and rebooting to try to find the right font to use.

Is there any way to turn off the lines altogether? If so, an option to do that would be great.

But, as requested in the original description…

Please would you add to the preview a section of the lines and corners, and the up- and down-arrows.

ok, I'll try to improve it a lttle bit
