This support was originally added to v6.18-rc1 of the Linux kernel:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=23743ba64709a9c137c1b928f8b8e00d846af9cc

However it only copied the regular screen buffer and ignored the Unicode 
screen buffer.  That was corrected by Nicolas Pitre in v7.0-rc5:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5eb608319bb56464674a71b4a66ea65c6c435d64

And the bug fix has been backported to v6.18.20 and v6.19.10.
