如何解决字体问题

我正在使用表格库阅读pdf

bot应该从pdf文件中读取表

我也使用pom.xml文件你知道吗

python 3.7.4版

我用烧瓶

我的代码：

import telebot
import os
import logging
import output
import timer
import script
import convert
import output
import settings
from time import sleep
from flask import Flask, request

bot = telebot.TeleBot(settings.API_BOT)
day = [1, 1, 2, 3, 4, 5, 6]
i_day = 4
line = 1


def file():
    global i_day
    global line
    script.SearchAndDownloadFile()
    convert.ConvertDocToPdf()
    output.Start()
    if day == 6:
        i_day = 0
        if line == 1:
            line += 1
        else:
            line -= 1
    i_day += 1


rt = timer.RepeatedTimer(43200, file())
try:
    sleep(10000)
finally:
    rt.stop()


server = Flask(__name__)


@bot.message_handler(commands=['start'])
def start_message(message):
    bot.send_message(
        message.chat.id, 'Привет ты написал мне /start , напиши и отправь название своей группы')


@bot.message_handler(content_types=['text'])
def send_text(message):
    if message.text in settings.GROUPS:
        output.Mess(message.text, day, line)
        for i in range(output.LEN):
            bot.send_message(
                message.chat.id, output.OUTPUT_MESS['message' + str(i)]['str_first' + str(i)])
    else:
        bot.send_message(
            message.chat.id, 'Упс, такой группы нет, пропробуй снова')


@server.route("/" + settings.API_BOT, methods=['POST'])
def getMessage():
    bot.process_new_updates(
        [telebot.types.Update.de_json(request.stream.read().decode("utf-8"))])
    return "!", 200


@server.route("/")
def webhook():
    bot.remove_webhook()
    bot.set_webhook(url="https://myapp/" + settings.API_BOT)
    return "?", 200


server.run(host="0.0.0.0", port=int(os.environ.get('PORT', 5000)))

函数文件不应影响速度，因为它将每12小时运行一次。此函数的第一个调用将在启动后12小时内进行 设置。你知道吗

API\u BOT是我的BOT令牌
