Installing foreign fonts into the yocto build

Installing foreign fonts into the yocto build

Hi Guys,

I have a small issue. On my device, I would like to have Chinese, Japanese,
Russian, Hebrewish, Greek fonts and all European language special
characters available for java application based on X.

In general I would like to know a method of adding custom fonts which are
scalable to X server. I tried browsing oever the internet and in the
mailing lists but not much success... Suggestions are deeply appreciated...

Regards,
Satya

I'm not much of an expert on this area, but it seems to me this is a pretty 
broad question; it covers not just fonts but also character sets. Presumably
if you can get away with only supporting Unicode you can just install a font
that supports a broad range of the unicode characters.

Otherwise, I'm not sure if there is a well-defined set of fonts to cover
everything; however one option would be to look at what fonts desktop-
oriented Linux distributions install by default since they always have to
deal with the issue of working out of the box in a wide variety of locales.

If you have an additional font to install that should be fairly easy - just 
copy one of the existing font recipes we have under meta/recipes-graphics/ttf-
fonts and edit it to suit the font. There are additional font recipes in the
meta-oe layer as well:

http://cgit.openembedded.org/meta-openembedded/tree/meta-oe/recipes-graphics/ttf-fonts

Once you have the recipe you just need to add it to the image, details on
how to do that can be found here:

There's nothing inherent about Poky / OpenEmbedded that means it doesn't 
support Unicode. Individual pieces of software might have difficulties however. 
I just copied over a text file containing "Schrödinger's 😻" (i.e. one German 
character and one special one) in UTF-8 to a core-image-sato image. The file 
doesn't display properly in the matchbox-terminal application (displaying 
garbage, indicating the encoding is incorrect), however in Notes (leafpad) it 
displays the ö but not the 😻 (displaying a single box with hex code instead, 
indicating that the font is missing that special character).

FYI I read this article recently and found it very useful - you may already 
know some or all of this, but just in case:

PS please keep the discussion on the mailing list, thanks.

FWIW, the terminal is based on libvte, so that *should* work.  Annoying.
