Hello,

The J-Link RTT Viewer does not support character encodings other than ASCII.
Currently, there are no plans to support other character encodings.

You may create your own application which interprets RTT data to suit your own needs.
This can be done by using
a) the TELNET channel of the J-Link software, for more information please refer to wiki.segger.com/RTT#TELNET_channel_of_J-Link_software
or
b) the J-Link SDK, for more information please refer to segger.com/products/debug-prob…nk/technology/j-link-sdk/
