Avoid the \r when applying a QRegularExpression to a sentence

I have extracted the following sentence :

Very important point. It should be discussed in our next meeting.

from the following line:

ID: 1 x: 1202 y: 2453 w: 242 h: 459 wn: 13 ln: 12 c: Very important point. It should be discussed in our next meeting.

using this QRegularExpression:

 regularExpression.setPattern("(?<=\\s)c:\\s?(.*)$");

However, the output is:

Very important point. It should be discussed in our next meeting.\r

The presence of the \r is quite normal because the line I am working with is written in a text file (Windows 8.1 Operating System).

Do you know how to extract the sentence without having the "\r" in the resulting output ? I really have no idea.

Thank you so much for your help

You can achieve that using a negated character class [^\r\n]:

regularExpression.setPattern("(?<=\\s)c:\\s?([^\r\n]*)");
                                             ^^^^^^^^

The [^\r\n]* subpattern matches zero or more characters other than \r and \n.
