DESCRIPTION

App::Greple::charcode displays Unicode information about the matched characters. It can also visualize zero-width combining or hidden characters, which can be useful for examining text containing such characters.

The following output, retrieved from this document for non-ASCII characters (\P{ASCII}), shows that the character \N{VARIATION SELECTOR-15} is included after the copyright character. The same character, presumably left over from editing, is also included after a normal ASCII t character.

$ greple -Mcharcode '\P{ASCII}' charcode.pm

        ┌───  12 \x{fe0e} \N{VARIATION SELECTOR-15}
        │ ┌─  14 \x{a9} \N{COPYRIGHT SIGN}
        │ ├─  14 \x{fe0e} \N{VARIATION SELECTOR-15}

The nasal sound of the K line (カ行) in Japanese is sometimes represented by adding a semivoiced dot to the K line character, and since Unicode does not define a corresponding character, it is represented by combining the original character with a combining character. This module allows you to see how it is done.
