I've got a new PC with Win 10.
In the SDA the Korean characters are now displaying as boxes, while other non-Roman scripts are ok. The Unicode codes are present and correct.
I've reinstalled the SDA, checked the fontconfig file is present on the PC and I've download the Windows language packs to no avail.
We used to have this sort of issue with Millennium yonks ago but no one has reported it recently.
Anyone got any helpful hints?
