python程序exe运行字符出现问号_字符仅在行尾显示为菱形问号（Python> Text）

I'm working on a Python file that inputs a text file with Japanese characters (UTF-8) in it, takes some of the text, and writes it into a new UTF-8 text file.

The problem I'm coming across is that for some reason whenever the Japanese character だ appears at the end of a line in the original input file, it comes out as a diamond question mark in the output file.

Instances of だ before the end of a line read perfectly fine and the original input file has it reading perfectly fine even if it's at the end of the line.

As you haven't shared any code snippet I would recommend you a generic way of reading and writing utf-8 files using the codecs module as:

# Reading utf-8 encoded file

with codecs.open("in.txt", "r", encoding="utf-8") as input_data:

data = input_data.read()

# Write utf-8 encoded file

with codecs.open("out.txt", "w", encoding="utf-8") as output_data:

output_data.write(data)

And BTW I tested it on the given character だ and it works pretty fine.
