Some characters not encoded

[Vanny-boy]

I'm using your notams API. Some characters, like the degrees symbol (°) are not showing up on the results of the query. Instead, a question mark like this (�) is displayed in the console-log result. Could you please get back to me with a solution for this? Thanks.

To my knowledge NOTAMs use a simplified character set and symbols like the degree symbol are usually not used. Something like a co-ordinate, N10° 10' 10'', E 010° 10' 10'' would appear in a NOTAM as N101010.0 E0101010.0

It is possible that domestic NOTAMs may use a different set of character conventions, but for international NOTAMs, everything is uppercase and you barely ever see any characters more complex than a slash or a dash.
