+Desc: A program to print the frequency of different UTF-8 characters

+Depends: glibc >2.35
+Info: Diacritical marks are found in Unicode blocks:
+ - U+0300-036F: Combining Diacritical Marks
+ - U+1AB0-1AFF: Combining Diacritical Marks Extended
+ - U+1DC0-1DFF: Combining Diacritical Marks Supplement
+ - U+20D0-20FF: Combining Diacritical Marks for Symbols
+ - U+FE20-FE2F: Combining Half Marks
