Re: [std-proposals] New printf/scanf modifiers

I chose those modifiers because they already existed in tables like
the one here (halfway down the page)


I didn't know there was yet ANOTHER committee for the printf family of
functions, I'll see if I can implement the change in my own version,
annoying that they used U8,U16 & U32 though, I once saw a vid where U
was used as a specifier for uuid_t and I rather liked that idea, I
wanted a fast custom printf, not a bogged down one by checking for
specifiers after the modifiers, so far I've gotten away with keeping
the options & modifiers in a separate set of checks from the
specifiers and the specifiers just ignoring unsupported options &
modifiers, with U8, U16 & U32 I'll have to do differently in order to
also support the U specifier. I suppose there's also the alternative
of just ignoring the standards since I'm using a separate name
(paws_printf,pawls_printf etc) but that also makes it less likely the
library I'm making will be used simply because of the different
standard, that and I'm used to using the standard modifiers, really
don't want to change my habits there
