Actually, "38.926832, -77.03201" syntax is quite standard for technical
presentation of geocoordinates. I agree, that it's very American in using
"." for decimal separator, but it's standard de-facto (for example, Google
uses it in queries and I use it in GvsY tool in URLs:
http://www.sergeychernyshev.com/maps.html#49.008084,8.403756 ;) ).
Another alternative is to use ";" as separator (I doubt somebody uses it as
decimal separator) so the result will be like this: "38,926832; -77,03201",
but I still think that checking if comma splits into only two parts and then
using previous example is best.
