Swiftmailer subject and weird whitespace problem

Question

Hey

When sending a message with swiftmailer or SmtpMailer, the subject has a weird whitespace.

The subject should look like this: "Newsletter October 2010 - Hello everyone" But looks like this: "Newsletter October 2010 - Hello everyo ne"

The whitespace always comes up the same place.

PHPmailer does not have the whitespace, but we need to use swift because of spam.

Hope you can help me.

Thanks,

Troels
