Subject: [PATCH] Merge pull request #21227 from
 sbwilson:fix_framework_unicode_headers

* fix unicode errors for framework headers

This would crash if the header file included non-ASCII characters. This change ensures that headers are read and written as UTF-8 encoded files instead of ascii.

* Adds spaces after commas
