Tag with apostrophe not accepted

in Italian language (in Article, editor block activated), if I add a TAG with apostrophe it is not accepted.

For example:
“Museo d’Arte” o “Luciano D’Addario”,…

If I add the same TAG in the Articles list (in Quick Edit) it is accepted.

The same TAG is stored without problems if you don’t use blocks.

In Italian the apostrophe is fundamental.

Is it possible to fix the bug?

Thank you!
