How Python decodes UTF8 Encoding in String Format

Question

Now there is a string of utf-8：

s = '\\346\\235\\216\\346\\265\\267\\347\\216\\211'

I need to decode it, but now I only do it in this way：

result = eval(bytes(f"b'{s}'", encoding="utf8")).decode('utf-8')

This is not safe, so is there a better way?

Answer 1

Use ast.literal_eval(), it's not unsafe.

Then you don't need to call bytes(), since it will return a byte string.

result = ast.literal_eval(f"b'{s}'").decode('utf-8')
