Removing Line Termination Characters from a String
A line termination character sequence is a character or character pair
from the set: \n, \r, \r\n, \u0085, \u2028, and \u2029.
Note: The character pair \n\r is considered a two-line terminator
character and therefore will be replaced with two spaces.
// Returns a version of the input where all line terminators
// are replaced with a space.
public static CharSequence removeLineTerminators(CharSequence inputStr) {
String patternStr = "(?m)$^|[\\r\\n]+\\z";
String replaceStr = " ";
Pattern pattern = Pattern.compile(patternStr);
Matcher matcher = pattern.matcher(inputStr);
return matcher.replaceAll(replaceStr);
}
