TinyMCE can break your searches

tinymce.md

TinyMCE will convert accents to HTML entities like:

à becomes á

So you see the problem there, you search in your database for "á" or even "a" (in case you are using unaccent), and you get nothing.

In my case, I was using full text search in Postgres, using the dictionary portuguese_unaccent (custom dictionary check here).

So keep in mind you can always make TinyMCE not convert stuff:

tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  entity_encoding: 'raw'
});
