Hello Pranav, and thanks for your interest. I'm not sure whether this
problem exists anymore; I just tried to recreate it and I also don't
experience any corruption of my data.

It sounds like you've done it correctly; the steps to reproduce used to
be creating a column with a particular collation, inserting text, and
then changing the collation for that column, causing the data to
seemingly change. As Marc noted in the tracker, it only applies when
changing the actual column, not database or table collations. Anyway, at
this point I can't reproduce it and may need to close the ticket
depending on any further input from the other developers.
