Currently I develop an OptionROM for a custom PCI-E device. In this OptionROM I want to publish a HII form for the device configuration. Therefore I use the "HiiAddPackages" in the driver's "EFI_DRIVER_BINDING_PROTOCOL.Start()" function. And everything works fine.
Now I want to use my local language in the OptionROM form. The problem is that my local language is not very often implemented in the UEFI Firmware by default. For these cases I've decided to publish the "SIMPLE_FONT" HII package with my language glyphs directly from the OptionROM code. And it worked fine until I noticed that UEFI firmware on different motherboards has different font saturation.
For example here are pseudo-graphics for the "1" code glyph in AMI and InsydeH2O firmware:
This gives me a problem, what font saturation should I use in my SIMPLE_FONT package. In any choice it would look good on some motherboards, but bad on others. I'm thinking that I should get some glyph bitmap and based on its saturation publish one font version or another. How can I do it? Or is there any other solution to this problem?
