This command _does_ print "2693;W" for me, as of the aforementioned commit,
assuming the input file is glibc's localedata/unicode-gen/EastAsianWidth.txt
(line 1210).

Note that the width of many codepoints, including this one, changed from narrow
to wide with Unicode 9.0. Compare these two files:

ftp://ftp.unicode.org/Public/8.0.0/ucd/EastAsianWidth.txt ("2670..269D;N")
ftp://ftp.unicode.org/Public/9.0.0/ucd/EastAsianWidth.txt ("2693;W")

Any chance you worked from a Unicode 8 (or older) EastAsianWidth.txt, rather
than the one in glibc's source?

(Also note that your grep command can easily miss matches, since the file
defines ranges. It's not the case with U+2693 though.)
