Issues that may occur when you use Outlook Mobile Access with mobile devices and with the iMode service from NTT DoCoMo (871187)

MORE INFORMATION

Emoji characters cannot be used in some sections of Outlook Mobile Access

Symptom

Emoji characters are the Japanese equivalent of emoticons. When you try to use an emoji character in an Outlook Mobile Access message on a mobile device from NTT DoCoMo, the emoji character turns into a question mark.

Cause

This issue is caused by the way that characters are encoded on the NTT DoCoMo mobile device. Emojis work correctly in the tasks, in the calendar items, and in the contacts sections of Outlook Mobile Access. However, emojis will not work in mail sections. By default, the UseRegionalCharset registry subkey is turned on so that Japanese users can use Japanese to send messages. Additionally, mail is encoded in ISO-2022-jp by default. Emojis are non-standard ISO-2022-jp and are not encoded correctly. If the UseRegionalCharset registry subkey is turned off, mail is encoded in UTF-8, and the emojis work. Emojis work in the tasks, in the calendar items, and in the contacts sections of Outlook Mobile Access regardless of the registry key setting because the items in these sections are all encoded in UTF-8.

Workaround

There is no workaround for this issue.
