Removes some common entities and high-ascii or otherwise nonstandard characters common in text pasted from Microsoft Word into a browser.
This function should NOT be used on non-ASCII text; it may and probably will butcher other character sets indescriminately. Use it only to clean US-ASCII (7-bit) text which you suspect (or know) may have invalid or non-printing characters in it.
