This is a little personal tool of mine. I use it when I need to debug my scripts which deal with text in various ways. I release it publicly, as it may become useful for someone else.
It gives very basic information on every Unicode character in the input, be it
stdin, a file or a set of files.
The whole script is just a single Perl file. It should work with a default Perl installation, no additional modules are needed.
If no arguments are passed, the standard input is analyzed. This is very useful in pipes and that's the main way I use the script. Alternatively, filenames can be given.
The tool is not finished yet. It should also:
- treat combining characters properly;
- treat all control characters properly (have I missed some?);
- recognize light terminal themes;
- do something else maybe?
