$table->changeColumn('length', 'varchar', 10)->setDefault(0);
converts to
which throws an error on UNSIGNED. Adding ->unsigned(false) to the statement above resolves the issue.

It doesn't "add" it as such. It's already there. Presumably you're changing a INT column which already has UNSIGNED to a VARCHAR.

For the most part, when you're changing a column, it attempts to keep as much of the original column config as possible. In addition to setting unsigned to false, the other workaround is to call ->resetDefinition() on it.

That said, I agree it would be illogical for a varchar column to keep the unsigned property so we'll try and address that. But, just be aware that sometimes when changing a column, you'll need to reset its definition or manually adjust the existing properties of it.

Thank you for reporting this issue. It has now been resolved and we are aiming to include it in a future XF release (2.1.4).

Change log:
When using the schema manager and changing an existing column to a non-int type, remove the unsigned property if set.
Any changes made as a result of this issue being resolved may not be rolled out here until later.
