Indeed. Much easier to use IPA here, but the likelihood people can write/read it is pretty low. I'm out of practice, but should be /æʒər/. Could also copy-paste that into here: http://ipa-reader.xyz/
I've noticed consistently that more British people are familiar with IPA, even passingly or badly, than Americans. I've never quite known why -- unless you do a language degree here you're never taught it formally, but it's usually in the dictionaries (e.g. the Oxford English dictionary) by every word, often with multiple forms for different geographic regions. I've never actually seen a real physical en-us dictionary -- does Marriam Webster (sic) do the same?
Amusingly, I don't ever remember a proper IPA pronuncation table in almost anything I used to learn English.
