How to make Azure Maps SymbolLayer display special characters

Kevin Cai 40

The SymbolLayer doesn't display special characters set in textOptions. Setting the text as "кв.7" would only display ".7" on the map. I also tried encoding the string with encodeURI but it doesn't display the decoded string.

How are you providing that text string? Are you escaping any special characters?

Azure Maps is based on MapLibre and there is an open request at https://github.com/maplibre/maplibre-gl-js/issues/2307. Are the characters you are wishing to show outside of the supported set? "Symbol layers can only render Unicode characters in the Basic Multilingual Plane (BMP, up to U+FFFF)" If so, this behavior is by design.

I tried to input Russian characters, which are in the BMP. But they don't show up on the map.

Hi @Kevin Cai Can you let us know which symbols you are trying to display through the Maps layer title?

@IoTGirl , do we have any additional restrictions on displaying Russian characters?

Hi Kevin, As I stated, The Azure Maps control is based on MapLibre so I would assume MabLibre has the same limitation on the Symbol Layer. You have still not provided the character code you are tesing with so I have no way to confirm this for you. Sincerely, IoTGirl

@IoTGirl Sorry for the late reply, I understand the limitation. The Russian characters I'm inputting are "Скв", I'm not escaping them. But I tried Chinese characters "你好" and they were able to be displayed, so I was wondering why this might be happening. Please let me know if you could reproduce this error. Thanks!

Can you clarify the character code for Cкв you think should work? I believe the Chinese characters are a BMP so supported but I believe the one you want is beyond U+FFFF
