bool startsWithLtr (String text, [ dynamic isHtml = false ])

Determines if the first character in text with strong directionality is LTR. If isHtml is true, the text is HTML or HTML-escaped.

  return new RegExp('^[^$_RTL_CHARS]*[$_LTR_CHARS]')
      .hasMatch(isHtml ? stripHtmlIfNeeded(text) : text);
}
