PutHtml() doesn't work with Unicode chars

[VladimirAlexiev]

(This is a repost of https://github.com/jkitchin/ox-clip/issues/2)

Expected behavior and actual behavior:

• I should be able to put HTML with Unicode chars on the clipboard
• If there are some Unicode chars, nothing is put on the clipboard (whereas it works with Unicode entities)

Steps to reproduce the problem:

• Save html-clip-w32.py as shown in https://stackoverflow.com/questions/76175244/how-to-put-formatted-text-on-clipboard-with-python-and-avoid-conflict-with-ditto. It's adapted from http://code.activestate.com/recipes/474121-getting-html-from-the-windows-clipboard, and shows author = "Phillip Piper", date= "2006-02-21"
• Save test.html:

  
  <p>
  ¡ ¢ £ ¤ ¥ ¦ § ¨ © ª « ¬ ­ ® ¯ ° ± ² ³ ´ µ ¶ · ¸ ¹ º » ¼ ½ ¾ ¿ À Á Â Ã Ä Å Æ Ç È É Ê Ë Ì Í Î Ï Ð Ñ Ò Ó Ô Õ Ö × Ø Ù Ú Û Ü Ý Þ ß à á â ã ä å æ ç è é ê ë ì í î ï ð ñ ò ó ô õ ö ÷ ø ù ú û ü ý þ ÿ
  </p>

let's try "quotes" and long—dash.

- run `python html-clip-w32.py < test.html`
- Nothing is put on the clipboard
- Remove the first paragraph and repeat the test
- This is put on the clipboard in HTML format: `let's try "quotes" and long—dash. `

In another case, this source

|  4 | Musée Royal d’Afrique centrale (MRAC)                       | Belgium |

comes out like this:
