rostopic pub does not allow carriage return or line feed in the string [closed]

edit

This would appear to be a duplicate of a question your posted yourself: #q335694?

And of #q248739, which afaict actually answers the question as well.

Assuming this is the case, I'm going to close this one as a duplicate.

I did ask the question before but it was not answered and it was marked as such. The issue you mention in the comment asks for a similar answer but again it was not answered for CR and LF.

I'm not sure I understand.

Afaict #q248739 shows how to encode newlines into strings passed to rostopic.

I did ask the question before but it was not answered and it was marked as such.

it doesn't seem to be marked as answered to me.

If something hasn't been answered, please update it. Do not post duplicates.

Also I would have reopened the issue back then but I was unable to. Just like this issue. I can't reopen this one either. I would just like an answer to the question. If it can't be done, fine.

I think I understand now the difference between something that has answers and the something that is answered. The latter has a check mark.

As for as #q248739 I still don't see how that allows be to send a string like "hello world\r\n"

Also I would have reopened the issue back then but I was unable to.

Your previous question wasn't closed. There is nothing to re-open as far as I can see.

Please update your original/previous question instead of posting this duplicate.
