MW version 1.34.2
page forms version: 4.9.5
When saving a page form containing a property with tokens, some characters are automatically replaced with entities, such as `Ø` -> ` Ø `. When an item with such an an entity is saved, the ampersand is again expanded to `Ø` breaking the first entity.
Here is a minimal reproduction of the issue on the Semantic Mediawiki sandbox.
Form: https://sandbox.semantic-mediawiki.org/w/index.php?title=Formulaire:Example_token_entities_form_bug
Edited Item: https://sandbox.semantic-mediawiki.org/wiki/Page_forms_token_error (Page_forms_token_error)
**Example**
From form create a new Item and add to property Example_tokens: øysters.
The form saves succesfully and the template looks like this if you visit the source tab:
```
{{Example token entities
|example_tokens=øysters
}}
```
Go to form, write page title, click edit or create. Click save page.
Output is saved as
```
{{Example token entities
|example_tokens=øysters
}}
```
The `&` in `ø` now has been replaced with `&` invalidating the html entity which was created on first save.
