bug#12285: uniq on a UTF8 file with roman numerals

[P. Michaud]

Hello,

I used the command

"uniq -dc myfile.txt'

here are some lines of the output

      2 ☼ turvy
      2 ☼ with gay abandon
      2 ☼ with reckless abandon
     10 ☼ yyⅰ
      9 ☼ yyⅹⅲ
      2 ☼ yyⅺ
     12 ☼ zzⅰ


The three first lines above are correct and correspond to real duplicates lines 
in the file, but the numbers on the 4 last one are erroneous, each of them 
correspond to a single line in the file.

Yours faithfully.

Pierre Michaud
