py包使用问题。在完全一样操作、代码，在昨天晚上可以正常运行，但是退出软件后到现在就一直报错。

1. 报错信息：(unicode error) 'unicodeescape' codec can't decode bytes in position 259-260: truncated \UXXXXXXXX escape

下面是代码

import openpyxl
import jieba

def main(args):
file_path = args[0] # 从参数中获取文件路径

# 打开 Excel 文件
wb = openpyxl.load_workbook(file_path)
ws = wb.active

# 查找 "来源名称" 所在列
col_num = None
for row in ws.iter_rows(min_row=1, max_row=1):
    for cell in row:
        if cell.value == "来源名称":
            col_num = cell.column
            break
    if col_num:
        break

# 如果找到了 "来源名称" 所在列
if col_num:
    # 转换列数为字母表示的列号
    col_letter = openpyxl.utils.get_column_letter(col_num)

    # 查找最后一个有值的列号
    max_col_num = ws.max_column
    while ws.cell(row=1, column=max_col_num).value is None and max_col_num > 1:
        max_col_num -= 1

    # 如果最后一个有值的单元格为空，则将分词结果写入该单元格
    # 否则将分词结果写入该列的下一列
    if ws.cell(row=1, column=max_col_num).value is None:
        for row in ws.iter_rows(min_row=2, max_row=ws.max_row, min_col=col_num, max_col=col_num):
            text = row[0].value
            if text:
                result = ' '.join(jieba.cut(text))
                row[max_col_num-1].value = result
    else:
        next_col_num = max_col_num + 1
        next_col_letter = openpyxl.utils.get_column_letter(next_col_num)
        for row in ws.iter_rows(min_row=2, max_row=ws.max_row, min_col=col_num, max_col=col_num):
            text = row[0].value
            if text:

                ws[next_col_letter+str(row[0].row)].value = result

# 保存 Excel 文件
wb.save(file_path)
