[issue22746] cgitb html: wrong encoding for utf-8

It does, in fact as long as the encoding used by the browser matches the one used in the file, no charrefs needs to be used (except > < and ").  Of course, if non-Unicode encodings are used, the range of available characters that can go directly in the HTML will be more limited, but this can be solved by using charrefs -- the browser will display the corresponding character no matter what is the encoding.  This also means that if charrefs are used for all non-ASCII characters, then the browser will be able to display the page no matter what encoding is being used (as long as it's ASCII-compatible, and most encoding are).  The downside is that it will make the source less readable and possible longer, especially if there are lot of non-ASCII characters, but if most of the characters are expected to be ASCII, using charrefs might be ok.
