Is it possible to make ofDrawBitmapString Utf8 aware.?

I am looking at ofBitmapFont.cpp to figure out how exactly ofDrawBitmapString works…

I am curious if it is possible to make it utf8 aware…

float posTexW = (float)(character % 16)/16.0f;
		float posTexH = ((int)(character / 16.0f))/16.0f;

		float texY1 = posTexH;
		float texY2 = posTexH+heightTex;

		//TODO: look into a better fix.
		//old ofDrawBitmapString was 3 pixels higher, so this version renders text in a different position.
		//3 pixel adjustment corrects that when y is flpped 5 when it's not.
		int yOffset = 14;
		if(!vFlipped){
			y += 5;
			y += yOffset;
			yOffset *= -1;
		}else{
			y -= 3;
		}

		int vC = vertexCount;
		charMesh.getTexCoords()[vC].set(posTexW,texY1);
		charMesh.getTexCoords()[vC+1].set(posTexW + widthTex,texY1);
		charMesh.getTexCoords()[vC+2].set(posTexW+widthTex,texY2);

		charMesh.getTexCoords()[vC+3].set(posTexW + widthTex,texY2);
		charMesh.getTexCoords()[vC+4].set(posTexW,texY2);
		charMesh.getTexCoords()[vC+5].set(posTexW,texY1);

		charMesh.getVertices()[vC].set(x,y);
		charMesh.getVertices()[vC+1].set(x+8,y);
		charMesh.getVertices()[vC+2].set(x+8,y+yOffset);

		charMesh.getVertices()[vC+3].set(x+8,y+yOffset);
		charMesh.getVertices()[vC+4].set(x,y+yOffset);
		charMesh.getVertices()[vC+5].set(x,y);

		vertexCount += 6;
	}

no, bitmap font is reallly simple it has a very reduced character set if you want to use utf8 you’ll need to use ofTruetypeFont and load a ttf that has that character set but this will only work with the nightly builds not with the current official release 0.9.8 which still doesn’t have that functionality.

:beer: good enough…
