Special sign

terefere

For example, sign for angle/temperature:  [backcolor=rgba(80, 151, 255, 0.18)]° Thier code is 0176. I can past this sign to text label from VTFT level, but how to use it from LUA level. Encoding look's fine- I can write in LUA my country letter but I cannot win with this sign... ;/

There is no way to get a control's color code from lua, and only some lua apis have color parameters, which generally need to be defined in lua

No no, misunderstand. I noo need to change color. I want to display special sign like this °  (celsius degrees) into LUA code.

[backcolor=rgba who you see is not my, probably forum add this text.

Suppose a text control with a screen ID of 1 and a control ID of 2 needs to display an Angle, you can write this in lua:

local temp = 30.0 .. "°"
set_text(1, 2, temp)
