The Unicode Description Utilities : A set of four programs for finding out what is in a Unicode file

The Unicode Description Utilities is a set of four programs for finding out what is in a Unicode file. uniname defaults to printing the character offset of each character, its byte offset, its hex code value, its encoding, the glyph itself, and its name. Command line options allow undesired information to be suppressed and the Unicode range to be added. unidesc reports the character ranges to which different portions of the text belong. unihist generates a histogram of the characters in its input. ExplicateUTF8 is intended for debugging or for learning about Unicode. It determines and explains the validity of a sequence of bytes as a UTF-8 encoding.

The SMS Server Tools send and receive short messages through GSM modems or mobile phones

The SMS Server Tools send and receive short messages through GSM modems or mobile phones. The user can send short messages by simply storing text files into a special spool directory. The program monitors this directory and sends new files automatically. It also stores received short messages into another directory as text files. The program can run other external programs or scripts after events like reception of a new message, successful sending, and when the program detects a problem. These programs can inspect the related text files and perform automatic actions.
