I think we're seeing the "Mary–marry–merry merger" (specifically the Mary–marry part). [1] claims about three quarters of American English speakers suffer from it.

I have heard nobody in the US pronounce the first syllable in "character" other than as rhyming with "air".
But yes, when I (rarely) have to pronounce it, it's "vairkair".

In the US, I’ve heard both.
I do.
Never met anyone who would rhyme the first syllable in "character" with "air" - maybe this is true in some US accents? I'm British and would say "character" as "kah-rik-tuh" or "kah-rak-tuh" which definitely has no "air" sound anywhere.
For me, by this logic, it would be "Vair-Kar"
