wrong linefeed under macOS is breaking the Accessibility APIs

G. | Last updated: Jun 03, 2022 09:19AM UTC

the linefeed under macOS should be `\n`. Burp seems to be enforcing the Windows linefeed, `\r\n`. that breaks the macOS Accessibility as it returns a length of 2 characters while `\r\n\` is actually one character. is there any way in Burp to enforce the linefeed to be the macOS standard? thanks.

Thanks for this report. We'll discuss this with our Burp Pro product team and get back to you.

Are you using the Repeater tool when you're seeing this issue? If you are, then if you click on the \n icon at the top of the request window you can display the non-printable characters and delete individual non-printable characters if this would help. If that's not quite what you're looking for can you send a few screenshots to help describe your scenario to support@portswigger.net, please? We can then take a closer look at what options are available for you.

hi Michelle! yes, this is what i'm talking about, and this is what i've done as a test. but that would be pretty cumbersome to remove the \r character for each line manually. there's no option anywhere in Burp to choose the encoding? is there maybe any plan to add something? thanks.

Thanks for the update. The use of /r/n comes from the HTTP/1 specification rather than being related to the OS-specific delimiter. Can you tell us more about the task you're carrying out? Are you using Burp's message editor? Are you using dictation or a screen-reader?
