To be consistent for horizontal hex you should represent U+11234 as either:
011
234
or
0001
1234
With vertical hex it is:
013
124
Once you get used to it, it makes lots of sense. For example it is sometimes used for ASCII or EBCDIC dumps:
This is a test
56672672627677
48930930104534
You could do a Unicode BMP as:
This is a test
00000000000000
00000000000000
56672672627677
48930930104534
For a full range Unicode as:
This is a test
00000000000000
00000000000000
00000000000000
00000000000000
56672672627677
48930930104534
The big advantage is that you see the original text as printable uinchanges and the hex descriptions as next to the character so you don't have scales an positions to count like other dump formats.

How many glyphs? Did it cover all possible characters?
