Assert error in bn_sprite_font's constexpr context about butano HOT 4 CLOSED

Hi,

Are you trying to create a new font?

Error logs seem to say that you are trying to render an invalid UTF-8 character and that the number of characters (ASCII + UTF-8) is different to the number of sprites in the spritesheet.

from butano.

I know the error it indicates in my new font but it is not the point that I want to report. According to the doc of BN_ASSERT, it can be used in constexpr contexts (is_constant_evaluated() returns true, but I still get the build error: call to non-'constexpr' function 'void __assert_func(const char*, int, const char*, const char*)'. I have already fixed the errors it asserts, but I think is_constant_evaluated may not work as expected.

Well, BN_ASSERT can be used in constexpr contexts, in fact the errors you are showing mean that constexpr asserts work.

It's just that the way the compiler shows that a constexpr assert has failed is not very friendly.

OK. I thought it will show the predefined info in the assert instead.
