[tex-live] Cannot run "TLmgr generate --rebuild-sys language" w/out error having added 8-bit Hebrew patterns

[Philip Taylor]

C:\texlive\2013\texmf-dist\tex\generic\hyph-utf8\patterns\tex contains
all standard hyphenation patterns :

C:\texlive\texmf-local\tex\generic\hyph-utf8\patterns\tex contains

The XeTeX format was dumped OK.  Is this because there needs to be a
non-UTF-8 version of "hyph-he.tex" and if so, how the h at ll does one
reverse-engineer a UTF-8 set of patterns into an 8-bit ASCII set ?!

I would prefer, of course, for 8-bit engines not to know about
"hyph-he.tex" at all; is that possible ?
