Problem with HTML entities

Hi,

I'm having an issue with html entities in my text blocks. When I first type an entity in, it is immediately replaced with the entity it represents inside the editor. For example, ® (&-r-e-g-;) is replaced with an r within a circle. I save it, it shows up fine on the site. Later, however, without anyone changing it, perch starts to display a weird character in front of it on the site.

In addition, sometimes it completely ignores the entities all together and just leaves them in their expanded ampersand form.

I changed the text block template by adding html="true". I thought that would help, but apparently not. Any idea how to fix this?

Thank you.

Bill
