How about moving the escaped-double-quotes into this format string?

#define PS_FMT "\"%ls\""
#define PS_FMT "\"%s\""

That'll make the call-sites look less wacky.

(I admit it doesn't really make any sense that we double-quote these paths in the first place. It's not as if we're going to actually escape the backslashes/quotes in the paths; so the quotation marks are kind of a lie. But I don't feel like unilaterally suggesting their complete removal.)

Personally I'd go the opposite way and rather see these macros closer to PRIxYYx macros (cf. and so not even include the % sign. This way, they could be used in the future with additional format options, like width, between % and the macro.

#define PS_FMT "ls"
#define PS_FMT "s"

And put % in the format string. WDYT?

Something along those lines were my original intent, but I don't object to going the other way and including more parts in the macro.

I'll leave resolving the rest of the bits in D98097 to you, thanks!
