Wrong display of letters with marks above (ščžáé...) - on the map

[CTJoriginal]

Street Complete displays text of letters with marks (čšžćá...) wrongly; instead of mark being above the letter it gets moved to right where it intercepts with next letter in line (check attached screenshots), which makes text verry hard to read. Issue only happens on text displayed on the map and not in input fields.

How to Reproduce
Create place (shop overlay) with name, that contains these letters

Expected Behavior
It's expected that these letters appear like this: ščžćáè...

Versions affected
Android: 13, ONE UI 5.1
App: v51.2

Do the names display correctly when you open the element?
If yes, it might be related to #4554 (which can't be fixed in SC)

[mnalis]

Yes, it would be interesting to know:

• what language is chosen in StreetComplete?
• at what location is that happening?

For me (SC v52.1, EMUI 12/Android 10?) with Croatian language, it works (and has always worked) just fine, e.g. at https://www.openstreetmap.org/way/591540390:

Looks fine for me too (Android 9)
Could be that it's broken on Android 12+ only? There were some font issues previously: tangrams/tangram-es#2303

[CTJoriginal]

It seems to happen in all languages for me

I have attempted reinstalling app and issue persists.

@Helium314 yes names display correctly when you open element

@mnalis It's happening in Slovenia

[matkoniecz]

Is it happening also with Polish letters? Such as Ś and ó?

I went ahead and tried all accents:

I also found out that names dont even display if they contain letters such as "ș ş" and any zalgo text (T̴̜͉̈́͐e̶̝̮̒ş̴̱̐̓t̵̙̐ ̴͔̹̍1̸̼̣̓2̷̳̞͛3̵̫̂). I guess it can't display text if it has marks bellow letter.

Right, anyway, the fact that it only happens for things rendered on the map but not in the UI means that it is a tangram-es issue and we can do nothing about this. So I'll close this as will-not-fix, as it is an upstream issue.

Unfortunately, tangram-es isn't really maintained anymore. I figure, you could post an issue there, but most probably it would just be for documentation purposes. It may also be just the same issue as tangrams/tangram-es#2335, so you could also just add a comment there.

[CTJoriginal]

Alright, I guess we will just have to live with it then.

@CTJoriginal you can try testing with testing .apk (can be run at the same time as original SC without affecting it) published in this issue:

• Explore migration from tangram to MapLibre #3123 (comment)

If it works ok in MapLibre part of the screen, than those display issues may be an additional argument for making the move from Tangrem-ES to Maplibre (especially as more and more devices are going to be Android 12+, and many languages contain non-ASCII names)

[CTJoriginal]

MapLibre version seems to work perfectly!

I also tried with greek letters "Σπιτική" from another issue

[soshial]

We also got this problem in Latvia :(
With street names and neighbourhoods.

[mnalis]

@soshial and what Android version is that (and what SC version)?

For me (SC 53.3 on Android 10/EMUI 12) the same region displays fine:

So far, it seem to be happening only on newer android versions. Unfortunately, as stated above, this is bug in Tangrem-es library, which seems to be abandoned, so it is very unlikely to be fixed. Possible solution is porting StreetComplete to use Maplibre instead of Tangrem-es, but that is no small job.

@mnalis

@soshial and what Android version is that (and what SC version)?

Street Complete v54.0
Samsung Galaxy S22 with Android 13

[RubenKelevra]

@soshial can you confirm that it's fixed in version 59.0 Alpha 1?

Here under Android 12 it looks fine now:

[mnalis]

For me (SC 53.3 on Android 10/EMUI 12) the same region displays fine:

And (again for me) on Android 14 it is broken (in all Tangram-ES versions, i.e. anything below v59.0-alpha1).

So it seems it broke with Android 13, and also it will be fixed with StreetComplete v59.0 release.

As e.g. shown here in that old testing version which displayed both Tangram-ES and MapLibre at the same time (this screenshot taken on Android 14):

one can clearly see Tangram-ES (left) side is broken, while MapLibre (right) side is fine.
If using Android 12 and below, both would be looking fine.

[soshial]

It looks like 59.0-alpha1 fixed it for my Samsuns S22 (Android 14).
Although, I haven't tested it with letters that have double diacritics (e.g. in Svan language or Livonian language). Have you tried it? Can't find such examples on a map.
Also, I couldn't find native titles on a map at all 🙃
