How to remove the nonprintlng characters?

[gnodet]

It looks like your terminal does not support bracketed paste. You can disable that using lineReader.unsetOpt(LineReader.Option.BRACKETED_PASTE). What kind of terminal are you using ?

[fqliao]

Linux, lineReader.unsetOpt(LineReader.Option.BRACKETED_PASTE) it does not work for me.

[fqliao]

Have any ways to solve the issue?

@fqliao Can you paste the full output of the infocmp command in your terminal ?

[gnodet]

Are you using a pipe / redirection or something like that ? The first characters are \E[?1h\E= and directly comes from the smkx configuration in your infocmp, so the terminal should definitely supports it.
