I made a 3D text created using textGeometry.

The problem is that the spaces in the letters are turned into question marks.

What can I do to solve this problem? This is my code.

    const loader = new FontLoader();
    const font = loader.parse(FontJSON);

    const textGeometry = new TextGeometry("abc de f", {
      font,
      size: 50,
      height: 10,
      curveSegments: 12,
      bevelEnabled: true,
      bevelThickness: 3,
      bevelSize: 1,
      bevelOffset: 0,
      bevelSegments: 12,
    });

    const textMaterial = new THREE.MeshNormalMaterial();

    textMesh = new THREE.Mesh(textGeometry, textMaterial);
    textMesh.position.set(0, 0, -240);
    textMesh.geometry.center();

    init();
