Try FreeTypeFont, FreetypeFont is available in maven repository so you can easily inject dependency through gradle in your project and use in your code.
public class MyGdxGame extends Game {
SpriteBatch spriteBatch;
BitmapFont font;
OrthographicCamera camera;
GlyphLayout glyphLayout,glyphLayout1;
String text,text1;
#Override
public void create() {
camera=new OrthographicCamera();
camera.setToOrtho(false,400,640);
spriteBatch = new SpriteBatch();
FreeTypeFontGenerator generator = new FreeTypeFontGenerator(Gdx.files.internal("Mangal.ttf"));
FreeTypeFontGenerator.FreeTypeFontParameter parameter = new FreeTypeFontGenerator.FreeTypeFontParameter();
parameter.color = Color.WHITE;
parameter.magFilter = Texture.TextureFilter.Linear; // used for resizing quality
parameter.minFilter = Texture.TextureFilter.Linear;
//ँंंःअआइईउऊऋएऐऑओऔकखगघचछजझञटठडढणतथदधनपफबभमयरलवशषसह़ािीुूृॅेैॉोौ्
parameter.characters = "शुभ प्रभात आप का स्वागत है"; //The characters the font should contain
parameter.size=15;
font=generator.generateFont(parameter);
font.getRegion().getTexture().setFilter(Texture.TextureFilter.Linear, Texture.TextureFilter.Linear);
font.setColor(1.0f, 0.0f, 0.0f, 1.0f);
generator.dispose();
text="शुभ प्रभात";
text1="आप का स्वागत है";
glyphLayout=new GlyphLayout(font,text);
glyphLayout1=new GlyphLayout(font,text1);
}
#Override
public void render() {
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
Gdx.gl.glClearColor(1,1,0,1);
spriteBatch.setProjectionMatrix(camera.combined);
spriteBatch.begin();
font.draw(spriteBatch,text,camera.viewportWidth*.5f-glyphLayout.width/2f,camera.viewportHeight*.5f);
font.draw(spriteBatch,text1,camera.viewportWidth*.5f-glyphLayout1.width/2f,camera.viewportHeight*.4f);
spriteBatch.end();
}
#Override
public void resize(int width, int height) {
camera.setToOrtho(false,width,height);
}
#Override
public void dispose() {
font.dispose();
spriteBatch.dispose();
}
}
Output looks like this :

We can use "Chanakya" font for render the Hindi Text in correct way. Download the chanyaka.ttf from hera :
http://indiatyping.com/index.php/download/199-chanakya-font
After installing the font . You should encode your Hindi text using the coverter :

Once converted the text, simply copy it to your destination and you should be good to go!
Enjoy :)
