Bash printf cannot handle any Unicode blocks starting with "Private Use Area"
(U+E000 - U+F8FF). Note I will be skipping the surrogate blocks[1] (U+D800 -
U+DFFF) for this post, as /bin/printf does not support them either[2]:

    $ bash -c 'printf \\uD7FF' | od -tcx1
    0000000 355 237 277
             ed  9f  bf

    $ bash -c 'printf \\uE000' | od -tcx1
    0000000 355 237 270 355 260 200
             ed  9f  b8  ed  b0  80

    $ /bin/printf '\uD7FF' | od -tcx1
    0000000 355 237 277
             ed  9f  bf

    $ /bin/printf '\uE000' | od -tcx1
    0000000 356 200 200
             ee  80  80

Tested with these environments:

    cygwin-20170119 bash-4.4.12
    cygwin-20170119 bash-4.4.11    
    cygwin-20170119 bash-4.4.5
    cygwin-20170119 bash-4.3.48
    cygwin-2.6.1 bash-4.4.12
    cygwin-2.6.1 bash-4.4.11
    cygwin-2.6.1 bash-4.4.5
    cygwin-2.6.1 bash-4.3.48
    cygwin-2.6.0 bash-4.4.12
    cygwin-2.6.0 bash-4.4.11
    cygwin-2.6.0 bash-4.4.5
    cygwin-2.6.0 bash-4.3.48

This appears to be Cygwin specific: I tested also on Debian 8.7.1 without issue.
