How to remove string "\u001b[1m" in java

After I receive a content response of the server, and print the content to console and I realize existing of the string "\u001b[1m", and I think it's the reason I can't parse the conte tresponse as a JSON object.

And I want to remove the string, any solution?

During the development of an SSH program that also utilizes command line mysql commands, I created the following regex that I strip these sequences with:

\u001b[\[\(]([0-9];[0-9]|\?[0-9]+)?[Bmh]

It covers the ranges that I have run into issues with

That's an escape sequence, and I think it's used to turn on formatting in some things like the Terminal. Is that really supposed to be JSON? What's the rest of the text? Does that escape sequence come as plain text or as one character?

Make sure you know what's actually in the string -- try examining (and maybe printing) it character by character using someString.charAt().

And, String newString = someString.replaceAll(oldexp); is one of many ways you might try to "fix" it, if it turns out that's needed.

That looks like an ANSI video escape sequence to turn bold mode on. Are you sure that the server is sending back a JSON object?
