Perhaps there is a utility or program that does this.
Have been working with web pages that have some utf-8
characters include. Came up with a program that process
files and creates report files that list all the lines and
positions that include utf-8 characaters. Then another file
that summaries each character with count. Then finally
will do the same and include the utf-8 description of the
character.
Found a list of all utf-8 2 byte 3 byte and 4 byte codes.
Turns out what I found was 122357 characters.
Unfortuntely, they were on pages that only listed around
a 1024? per page, so had to merge it all into a file that
turns out to be 4.4M in size....
Example of process.
218544 allraw.uog (combination of 64 web pages)
2000 allraw.uog.out (contains a total of 2000 uft-8 characters)
28 allraw.uog.out-sum (the 2000 character are 28 uniq ones)
28 allraw.uog.out-sum2 (list with names)
633 uog.csv (I extract 633 lines of contact data)
7 uog.csv.out (Only 7 lines with utf-8 characters)
3 uog.csv.out-sum (Only 3 uniq utf-8 characters
3 uog.csv.out-sum2 (list with names)
122357 utf-8codeslook.csv (4.4M file that has hex codes and des)
Example:
uog.csv.out
131 27 c3b1 [ñ]
131 51 c3b1 [ñ]
276 14 c3a5 [å]
344 18 c381 [Á]
344 29 c3b1 [ñ]
344 48 c381 [Á]
344 59 c3b1 [ñ]
uog.csv.out-sum
2 c381 [Á]
1 c3a5 [å]
4 c3b1 [ñ]
uog.csv.out-sum2
2 c381 [Á] LATIN CAPITAL LETTER A WITH ACUTE (U+00C1)
1 c3a5 [å] LATIN SMALL LETTER A WITH RING ABOVE (U+00E5)
4 c3b1 [ñ] LATIN SMALL LETTER N WITH TILDE (U+00F1)
Those are real simple.
The all file has 28 characters that include some strange ones.
5 e2808b [] ZERO WIDTH SPACE (U+200B)
1 e28092 [‒] FIGURE DASH (U+2012)
44 e28093 [–] EN DASH (U+2013)
2 e28094 [—] EM DASH (U+2014)
Not clear what the Zero Wicth Space is for?
The other 3 here all look the same to me??
Guess just needed to do something. Interesting result.
Progam takes the filename as input and creates the other 3 files.
If utf-8codeslook.csv in directory it creates the sum2 otherwise
skips it. Nice to have long description on some?
File is 4.4M but compresses to 510K as .xz file.

Perhaps someone else would find it useful, or perhaps
something exist that does something similar that I wasn't
able to find. Some mentioned have run across weird files
with utf-8. Seems to work for what I want.
Was fun figuring it out.
Thanks for your time.
Would be happy to make utf-8codeslook.xz file available
since it was a pain to add all the data from over 100
pages. Could find a single page with the data??
First 5 lines
c280;<control> (U+0080)
c281;<control> (U+0081)
c282;BREAK PERMITTED HERE (U+0082)
c283;NO BREAK HERE (U+0083)
c284;<control> (U+0084)
Some descriptions are almost 500 characters??
