Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

... and the usefulness of this is...?

Comment by atoponce 405 weeks ago

I have had practical use for this. Needed to find all characters used in the texts for a computer game to make sure our font included all needed glyphs.

Passed all texts through sed and then let "sort --unique" find all needed letters.

Another way to do this

echo Print text vertically| fold -c1

OS X's sed doesn't interpret \n in the replacement pattern, but you can use `sed $'s/./&\\\n/g'`.

& is the matched pattern, like $& in Perl and Ruby.

If LC_CTYPE is not already set to a UTF-8 locale, you can use `LC_CTYPE=UTF-8 sed` to make sed treat multibyte characters as single characters.
