Review Request #2405 — Created Oct. 21, 2019 and discarded
Mark "private use area" characters as printable.
At least some of the characters in E000-F8FF range are used by Powerline
fonts, and having no attributes for these ranges in UnicodeData.txt
other than "Other, Private Use" it should be safe to mark all of them as
printable as it's apparently what linux does, and the same change was done
in FreeBSD (as requested by users).
Check the character in private usage areas to have graph/print classes.
