There's this funny little system in Greece (more common in some places than in others), where some minor streets will be named after the main street from which they branch out: "X Street" will have branches "1st X Side-Street", "2nd X Side-Street", and so on. In Greek, that will be written with Greek numerals, like this: "Οδός Χ" and its subsidiary "Α΄ Πάροδος Χ", "Β΄ Πάροδος Χ" etc. Until recently, the keraia character (΄) appeared correctly next to its respective letter, as in the preceding examples. Now it appears above them, as in the following image (see "Α΄ Πάροδος Προύσης", "Α΄ Πάροδος Ζαλόγγου" and "Γ΄ Πάροδος Ζαλόγγου").

What's changed? And how can it be fixed?

Probably a question for (the map stylesheet for the standard layer) since this is not a map data issue.

Looks like a bug. Perhaps add it as a new 'issue' at ?

It renders wrong in the standard and humanitarian maps, but ok in the cycle and tranport maps.

The behaviour depends on which precise character is used for the keraia. In the examples above, it is Unicode U+0384 GREEK TONOS. I also checked another object I had created (in Cyprus) that has U+00B4 ACUTE ACCENT: this also behaved in the same way (accent typeset above the character, extra space after it).

However, according to, 'The modern keraia is a symbol (ʹ) similar to the acute accent (´), the tonos (U+0384,΄) and the prime symbol (U+02B9, ʹ), but has its own Unicode character as U+0374.'

So, I have modified way 100506456 ( to use the correct character U+0374 GREEK NUMERAL SIGN, and it now renders correctly.

The trouble is, there may be no easy way of entering this symbol on standard Greek keyboards!
