ghi07 on "[Plugin: Jetpack by WordPress.com] Contact email subject garbled if site title has apostrophe"

Hello Jeremy.
I've set up a demo site here: http://www.demo.angeles-hill.com/
The site title is St Michael's Men's Choir.

Here's the shortcode generated for the contact form:
[contact-form subject='[St Michael%26#039;s Men%26#039;s Choir'][contact-field label='Name' type='name' required='1'/][contact-field label='Email' type='email' required='1'/][contact-field label='Comment' type='textarea' required='1'/][/contact-form]

When I receive the email, the subject is:
’[St

Please let me know if you need anything else.
Cheers, Greg.
