I came across some invalid data in OSM, and while trying to investigate that came across some Irish relations https://www.openstreetmap.org/relation/14571417/history and https://www.openstreetmap.org/relation/14574362. In both cases it looks like what is now ref:name hasn’t been properly converted from UTF-8 at import**.
I presume that in both cases ref:name should be the correct (Irish) name of the town?
Edit:
Also https://www.openstreetmap.org/way/1093798199/history, https://www.openstreetmap.org/way/1094051558/history
** in both cases the original adder of the data was someone working for Microsoft - insert your own “Micros~1” joke here. ![]()
