In a continued push to support as many languages as possible, we’ve just pushed a small update live that improves our support for foreign characters in your campaign subject line. This update ensures all Asian character sets like Chinese, Japanese and Korean are fully supported. As usual, we’re using UTF-8 encoding for both the subject and campaign content.
As you can imagine, it can be difficult to test all the different language variations out there, so if you ever spot a discrepancy, please let us know and we’ll continue making tweaks and improvements to make sure everyone’s covered.
