I'm from Europe and my language doesn't have an equivalent to "coding" but i'm still using the English word "coder" and "coding" for decades - in my case i learned it from the demoscene where it was always used for programmers since the 80s. FWIW the Demoscene is (or was at least) largely a European thing (groups outside of Europe did exist but the majority of both groups and demoparties were -and i think still are- in Europe) so perhaps there is some truth about the "coding" word being a European thing (e.g. it sounded ok in some languages and spread from there).
Also in my ears coder always sounded cooler than programmer and it wasn't until a few years ago i first heard that to some people it has negative connotations. Too late to change though, it still sounds cooler to me :-P.
