I'm formatting an online poem that uses blackout text for erasures. My plan is to use an XML block character ( █ `█`) or `█`) to replace the appropriate characters. Does this have any specific impacts on accessiblity? I'm especially curious how screen readers will handle it. I found [this recent article][1] but the block character is not addressed.
