Reading utf-8 escape sequences from a file

问题:

I have an utf-8 encoded file that contains multiple lines like

\x02I don't like \x0307bananas\x03.\x02
Hey, how are you doing?
You called?

How do I read the lines of that file to a list, decoding all the escape sequences? I tried the code below:

with codecs.open(file, 'r', encoding='utf-8') as q:
    quotes = q.readlines()

print(str(random.choice(quotes)))

But it prints the line without decoding escape characters.

\x02I don't like \x0307bananas\x03\x02

(Note: escape characters are IRC color codes, \x02 being character for bolded text, and \x03 prefix for color codes. Also, this code is from within my IRC bot, with the MSG function replaced by print())

According to this answer, changing the following should have the expected result.

In Python 3:

codecs.open(file, 'r', encoding='utf-8') to

codecs.open(file, 'r', encoding='unicode_escape')

In Python 2:

codecs.open(file, 'r', encoding='string_escape')

If you want to output text to console with the same formatting, then the point is, that UNIX (or what OS do you use?) uses ANSI escape sequences different from those in IRC, so you have to translate IRC format to UNIX format. these are the links to start:

If you want to print text without formating, just clean it, by using regexp.
