Notification Bug

I've found a bug in the plugin:

When your form element has a space between it, in other words when your form element consists of two words, when you insert the element in the email subject line, the email is not sent to the desired email address.
I tested it with non-english words. For example test this:
{خدمات درخواستی: 13}
The space between خدمات and درخوساتی prevents the form being emailed.
It took me around 4 hours to figure it out. I completely redesigned a long form to figure out why my emails weren't coming through.

Update: Voila!
I found the problem!!
The problem occurs when the subject line is more than a certain number of words.
To be more specific the problem occurs when their is a combination of words and form element values exceeding a certain number of subject line characters, or if the form element value itself is more than a certain amount of characters.

It had nothing to do with the space between the element words etc..

What should I do to fix this?
How can I increase the number of characters/words allowable for the subject field of email notifications?

I'm the Farsi developer of CF7. CF7 doesn't have such a problem. It too uses the wp_mail function.
Thanks for your concern

A blank CSV is generated (0 kb in size).
I've contacted the CF7 developer to see if he has run into this problem before and will get back to you once I've got an answer.

Carl,

I sent the form XML to your email address. Please confirm.

درخواست خدمات ترجمه فارسی به انگلیسی
درخواست خدمات is just a text written at the beginning of the subject line
ترجمه فارسی به انگلیسی comes from a variable I inserted in the notification.
It's actually a drop down field value a user selects.

So very eagerly waiting for Gravity Forms with RTL support to come out.. Hmmm.. I wonder when..
