It would almost certainly depend on the character. In a good nations like Andoran or Lastwall, she may be misconstrued as some form of angel or aasimar, which would bring special treatment until her fiendish nature was exposed. In Cheliax, due to the presence of strix, she may be seen as one, even if she looks nothing like one, and arrested or attacked.

Given the relative racial diversity of Golarion as a whole, most common-folk would likely assume the character was somehow supernatural (for e.g., they were an angel or angel-descended) and make assumptions based on local tradition, but beyond that no general reaction. As Simeon pointed out, this largely depends on where. In Cheliax, they might get a lot of hate because of similarity to a Strix, and depending on where they were, nobody might have actually seen a Strix and thus be able to make the distinction. In Ustalav you'd get weird looks...but so does everyone in a country where a healthy dallop of terror-induced paranoia is the norm. More free-form places like Andoran, Absalom, or the River Kingdoms wouldn't give a fig. They'd make some weird assumption, then immediately dismiss it in favor of "but will they pay for my drink if i ask?" In Katapesh, that character might be targeted by slavers for looking exotic.
In some places in Tian Xia, some people would be confused by the mere suggestion that this is even unusual to begin with, that land being so inundated with outsiders and other supernatural influences even on the rural level.
Reaction, like real estate, is all about location, location, location.
I’d bet that inns have it rough, though, with all that cleaning up.
