Just downloaded Logos [edit]4.3 Beta 8 and saw the personal book function so I tried creating my own book. I am currently a missionary in Cambodia and so the first book I tried to import was one in Khmer (UTF-8). Logos is unable to display Khmer Unicode correctly.
Here is the first page in Word: http://www.actioncambodia.org/word-khmer.jpg
And here is the first page in Logos: http://www.actioncambodia.org/logos-khmer.jpg
Not sure if books can be shared, but I think this is the personal book file: http://www.actioncambodia.org/Khmer-Greek-Grammar-Personal-Book-Test.zip
I would be happy to help in any way I can to help Logos be compatible with Khmer Unicode.
Thanks,
Nathan
