Korean characters do not display properly in Lotus Notes when sent from iNotes

Technote (troubleshooting)


When a Lotus iNotes ultra-light mode user sends an email to a Notes recipient using Korean DBCS (Double-Byte Character Set) font, the text appears as boxes or as "numbers" in Lotus Notes.


To send DBCS fonts from an iNotes ultra-light mode client, UTF-8 must be enabled in the Server Document under Internet Protocols > Domino Web Engine, "Character Set" section. If UTF-8 is not enabled, then the Korean characters will show as "numbers" in both iNotes and in Lotus Notes.

However, if UTF-8 is enabled, the Korean fonts will show properly in iNotes, but will appears as boxes in Lotus Notes.


Lotus Notes 8.x/8.5.x

iNotes ultra-light mode 8.5.x
