BreakIterator.GetBoundaries is exponentially slow depending on the size of the source text #127
Description
Describe the bug
BreakIterator.GetBoundaries is exponentially slow depending on the size of the source text. In other words, the larger the size of the text parameter string is, the slower the function is, and the curve is not linear.
To Reproduce
string content = "... some large text, about 100KB ... ";
BreakIterator.GetBoundaries(BreakIterator.UBreakIteratorType.WORD, new Locale("eng"), content, false); // Takes about 10 secs.
Expected behavior
The BreakIterator.GetBoundaries to finish within milliseconds.
Environment
