I was in the process of creating a function in my compute shader that converts a 180° angle to a 360° CCW angle like this:
// Calculates the 360° angle counter-clock-wise
float angle360(in float2 a, in float2 b)
{
float angle = angle180(a, b);
// Right hand rule: When b is to the left of a, a x b points up -> take the "opposite" of the 180° angle in the 360° "space"
if (cross(float3(a, 0), float3(b, 0)).z > 0)
angle = 360 - angle;
return angle;
}
But when I went back to the Unity Editor it complained to me that there was a "unrecognised identifier 'INVALID_UTF8_STRING' at kernel CSMain" on line 1
When I deleted the comments the error went away, and it doesn't happen with any other comment, only these, and they are also the only ones that contain the °
character. So my question is, why doesn't the shader compiler (I assume) like that I use this character?
