Update convert_chars():

Browse Source 
- Stop trying to remove `<title>` and `<category>` meta tags. They have not been used for many many years.
- Replacement of `<br>` with `<br />` and `<hr>` with `<hr />` is not needed for HTML 5.0. Also, these tags are formatted like that by the visual editor.
- Replace invalid HTML entities that might be pasted in the Text editor on save instead of on display.
Fixes #32335.
