html entities in permalink and extraneous forward slash and dash

Hi Jeff, 

Thanks so much for the report and code suggestions. 

There might be even more HTML entities so we decided to call html_entity_decode() so unknown chars can be filtered out and we don't to list them all in autopopulate_skipWords.

Can you try the attached plugin and let me know if resolves the issue for you?  If so we'll release this update.

This line is actually dash not underscore which is a good thing, but removing the underscores would also be good

$permalinkText = preg_replace("/(^-+|-+$)/", '', $permalinkText);           // remove leading and trailing underscores

should be

  $permalinkText = preg_replace("/(^-+|-+$)/", '', $permalinkText);           // remove leading and trailing dashes
  $permalinkText = preg_replace("/(^_+|_+$)/", '', $permalinkText);           // remove leading and trailing undeerscores

There is some debate on whether underscores should be replaced with dash.

Replacing & with 'and' can lead to poor a permalink, i.e. good&bad gets converted to goodandbad where good-and-bad would be better.

Anyway, that's what I came up with so far.

Hi Jeff, 

Thanks for the feedback! We've released permalinks v1.12 with the following changes: 

- Automatically remove “smart” ‘quotes’ instead of encoding them as HTML entities (lsquo, rsquo, etc.)
- Automatically remove periods when creating permalinks
- Add spaces when replacing & so "this&that" becomes "this-and-that" instead of "thisandthat"
- Misc Code and other minor improvements
