How to split string preserving whole words?

Question

I need to split long sentence into parts preserving whole words. Each part should have given maximum number of characters (including space, dots etc.). For example:

While CsConsoleFormat† was primarily designed to format text for console, it supports generating plain text as well.

var doc = new Document().AddChildren(
  new Div("Silver badges are awarded for longer term goals. Silver badges are uncommon.") {
    TextWrap = TextWrapping.WordWrap
  }
);
var bounds = new Rect(0, 0, 35, Size.Infinity);
string text = ConsoleRenderer.RenderDocumentToText(doc, new TextRenderTarget(), bounds);

And, if you actually need trimmed strings like in your question:

List lines = text.Trim()
  .Split(new[] { Environment.NewLine }, StringSplitOptions.None)
  .Select(s => s.Trim())
  .ToList();

In addition to word wrap on spaces, you get proper handling of hyphens, zero-width spaces, no-break spaces etc.
