Re: [PATCH v5 0/2] MR5633: win32u: Use the first vertical alternates table regardless of script.

[Akihiro Sagawa (＠sgwaki)]

I created a vertical writing demo and attached it to the bug report --- https://bugs.winehq.org/show_bug.cgi?id=56658#c4 .

I hope this helps you to test my patch in your environment.
