http://tiles.wmflabs.org/hikebike/12/2263/1423.png "Bencebaráti", but freshly rendered tiles show the same.

There is no contact on Hike & Bike map tiles (neither in attribution nor in OSM wiki) so please forward this to the appropriate person, if any.

HikeBikeMap (hikebikemap.{de,com}) seems to have lost UTF8 capabiliy and throws undisplayable glyphs for UTF8 codes, probably interprets as 8859-1 or like. Probably that's a recent issue.

Cannot reproduce on http://www.hikebikemap.org/ as the name "Bernecebaráti" is displayed correctly. Firefox 32 on Fedora 20.

If you use a different system or there are different steps to reproduce: Please share that info.
Comment 2 Peter Gervai (grin) 2014-09-23 20:31:57 UTC
Have you tried to retrieve the specific tile I've shared?

http://tiles.wmflabs.org/hikebike/12/2263/1423.png

I actually tried to find a part which was not cached (Z20 somewhere around) and it was generated with bad encoding.
Comment 3 Peter Gervai (grin) 2014-09-23 20:35:18 UTC
I am using the tile server with leaflet and not the referenced website. Still, try to find some tiles not yet generated since it is probably a recent problem (so most of the old cached tiles seem to be okay).

Yeah, but how would I "normally" be able to access that in a web browser if I was a user and wouldn't know that "direct" URL to that tile?
"Steps to reproduce", so to say.
Comment 5 Andre Klapper 2014-09-23 21:36:33 UTC
Uh. I see the problem now when going to http://tiles.wmflabs.org/osm/slippymap.html (e.g. with cities in Western Czech Republic)

The problem seems related to the zoom level (and hence to the font?).

Not totally sure who is involved; CC'ing Colin here as a wild guess.
Comment 6 Peter Gervai (grin) 2014-09-23 22:08:01 UTC
Oh I quickly realised that you're not familiar with the OSM internals, sorry. :-)

Thanks for trying to find someone involved. Probably something was upgraded which broke the strings, it could be fun to find out but it's pretty easy to test (for someone knowing the internals).

(Sidenote: the tiles are used directly in most cases eg. an external website displays a slippy map addressing the tiles directly. See example at 
http://grin.hu/maps/osm/map1.html#zoom=14&lat=48.01533&lon=18.89339&layer=HikeBikeMap&overlays=FTFFFFFFFF )

I am not exactly sure what happened to cause this issue in the first place, but I am hoping it should be fixed now.

It might still take a couple of days to rerender all of the tiles that broke, but all newly rendered tiles should hopefully be OK.

If you spot any tiles that were rendered since today and are still showing the broken fonts, please let me know.

That doesn't sound very good. Self-healing issues are rare, so either someone is fiddling with dependent packages in the background and they don't tell you or something truly magical goes on.

They are correct, I have verified it.

Looks ok to me.

However please provide some info on the hikebikemap.de / osm wiki about how to report hikebike issues, since - as you see up here - people are puzzled about who is responsible, what is it and it's not even clear (to the OSM community) where and how to report issues. I'm lucky that I'm quite familiar with both projects and being assertive enough to push it but others may not be that lucky. :-)

As a starter I don't know out of the top of my head who you might be, but possibly a brief search will reveal that. :-P
