Well this can be any ui.Image banner. I just wanted to make a banner image for what I am working on at the moment. I have seen the draw_as_pattern Image method before. I just never tried it. There is more to draw_as_pattern than what I have done here.
Yes it's simple, but sometimes it's what you need.
Just share incase it's useful to anyone 

import ui

def emoji_to_image(emoji_char, w =32, h=32,
                font_name = 'Arial Rounded MT Bold',
                font_size = 28, file_path = None):

    r = ui.Rect(0, 0, w, h)

    with ui.ImageContext(r.width, r.height) as ctx:
        # just draw the string
        ui.draw_string(emoji_char, rect=r,
        font=(font_name, font_size), color='black',
        alignment=ui.ALIGN_CENTER,
        line_break_mode=ui.LB_TRUNCATE_TAIL)

        img = ctx.get_image()

        # write a file if file_path
        if file_path:
            with open(file_path, 'wb') as file:
                file.write(img.to_png())

        return img

def pattern_image(ui_image, w, h):
    with ui.ImageContext(w, h) as ctx:
        ui_image.draw_as_pattern(0, 0, w, h)
        return ctx.get_image()

def create_emoji_banner(emoji_char , w, h, img_w, img_h):
    img = emoji_to_image(emoji_char, w = img_w, h = img_w)
    return pattern_image(img, w, h)


if __name__ == '__main__':
    w = ui.get_screen_size()[0] * .7
    h = ui.get_screen_size()[0] * .2
    img = create_emoji_banner('🏁', w, h, 36, 36)
    img.show()

    img = create_emoji_banner('🇫🇷', w, h, 56, 56)
    img.show()

    img = create_emoji_banner('🕐', w, h, 32, 32)
    img.show()
