Summary

To expand the range of ad expressions in Display Ads, we support the addition of emojis in the ad titles and the item name of the Dynamic Ads for Display. In addition, we have added symbols available in ads, relaxed the rules for symbol use, and added character codes in the import and export features of the Campaign Editor.
