UnicodeDecodeError：“ utf-8”编解码器无法解码位置359中的字节0x92：无效的起始字节

Question

第一次海报，请和我一起...

#!/usr/bin/python
import sys, os
count = 0
filename = "data2.txt"
file = open(filename, "r")


s1 = input("What do you want to search for? ")
search = s1.lower()

words = search.split()

def restart_program():
    """Restarts the current program.
    Note: this function does not return. Any cleanup action (like
    saving data) must be done before calling this function."""
    python = sys.executable
    os.execl(python, python, * sys.argv)

def countlines():  #count length of file
    with open(filename, 'r') as f:
        count = 0
        for line in f:
            count += 1
        return count
total = countlines()
totp1 = total + 1

with open(filename) as f:
  currpos = 0
  for line in f:
    currpos += 1
    line2 = line.lower()
    if currpos < totp1:
      if len(search.split()) == 2:
        if line2.find(words[0]) != -1 and line2.find(words[1]) != -1:
          print(line)
      if len(search.split()) == 1:
        if line2.find(search) != -1:
          print(line)
          #restart_program()
      if search == "quit":
        print('Exiting')
        break
      if search == "exit":
        print('Exiting')
        break
    if currpos == total:
      restart_program()

当我在Repl.it上运行此代码时，它可以毫无问题地运行，并且可以正常运行。但是，当我在笔记本电脑（Arch）上运行它时，出现此错误：

    Traceback (most recent call last):
  File "./search", line 23, in <module>
    total = countlines()
  File "./search", line 20, in countlines
    for line in f:
  File "/usr/lib/python3.8/codecs.py", line 322, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x92 in position 359: invalid start byte
