i'm trying to code a chess game in python 3.11, currently im stuck drawing the chess pieces on the bord

Question

i'm trying to make a chess board using python 3.11 and the sys and pygame libraries, i tried using unicode to print the pieces on the board but as seen on the image bellow this didn't go as planned.

the chess board, the blocks on the board are the pieces i'm trying to draw

import sys, pygame as pg

pg.init()
screen_size = 750,750
screen = pg.display.set_mode(screen_size)
pg.font.init()
playing = True

#tile fill list
set_font = pg.font.match_font("Arial Unicode MS")
font = pg.font.Font(set_font, 25)
chess_pieces = {
    'b_checker': u'\u25FB',
    'b_pawn': u'\u265F',
    'b_rook': u'\u265C',
    'b_knight': u'\u265E',
    'b_bishop': u'\u265D',
    'b_king': u'\u265A',
    'b_queen': u'\u265B',
    'w_checker': u'\u25FC',
    'w_pawn': u'\u2659',
    'w_rook': u'\u2656',
    'w_knight': u'\u2658',
    'w_bishop': u'\u2657',
    'w_king': u'\u2654',
    'w_queen': u'\u2655'
}

number_grid = [
    ['b_rook', 'b_knight', 'b_bishop', 'b_queen', 'b_king', 'b_bishop', 'b_knight', 'b_rook'],
    ['b_pawn', 'b_pawn', 'b_pawn', 'b_pawn', 'b_pawn', 'b_pawn', 'b_pawn', 'b_pawn'],
    ['Null', 'Null', 'Null', 'Null', 'Null', 'Null', 'Null', 'Null'],
    ['Null', 'Null', 'Null', 'Null', 'Null', 'Null', 'Null', 'Null'],
    ['Null', 'Null', 'Null', 'Null', 'Null', 'Null', 'Null', 'Null'],
    ['Null', 'Null', 'Null', 'Null', 'Null', 'Null', 'Null', 'Null'],
    ['w_pawn', 'w_pawn', 'w_pawn', 'w_pawn', 'w_pawn', 'w_pawn', 'w_pawn', 'w_pawn'],
    ['w_rook', 'w_knight', 'w_bishop', 'w_queen', 'w_king', 'w_bishop', 'w_knight', 'w_rook']
]

def draw_pieces():
    offset = 35
    for row in range(8):
        for col in range(8):
            output = number_grid[row][col]
            if output != 'Null':
                if output in chess_pieces:
                    output = chess_pieces[output]
                piece_surface = font.render(output, True, pg.Color('black'))
                screen.blit(piece_surface, (col * 90 + offset + 5, row * 90 + offset - 2))

def draw_background():
    screen.fill(pg.Color("burlywood2"))
    pg.draw.rect(screen, pg.Color("burlywood4"), pg.Rect(15, 15, 720, 720), 7)
    i = 1
    for i in range(1, 8):
        pg.draw.line(screen, pg.Color("burlywood4"), pg.Vector2((i * 90) + 15, 15), pg.Vector2((i * 90) + 15, 730), 2)
        pg.draw.line(screen, pg.Color("burlywood4"), pg.Vector2(15, (i * 90) + 15), pg.Vector2(730, (i * 90) + 15), 2)

def game_loop():
    for event in pg.event.get():
        if event.type == pg.QUIT:
             sys.exit()

    draw_background()
    draw_pieces()
    pg.display.flip()

while playing:
    game_loop() 

so i tried finding a solution using chatGPT, the only solution it gave was that i might need to change the font in this line of code:

set_font = pg.font.match_font("Arial Unicode MS")

i'm not familiar with working with fonts but i tried different fonts and they all gave the same result
