Package: utfcheck (1.2-2)

check validity of UTF-8 and ASCII files

The utfcheck program examines a text file and prints a summary of what the file contains: ASCII, UTF-8, UTF-16 (either big-endian or little-endian based on an initial Byte Order Mark), or binary data. ASCII and UTF-8 files are processed further; UTF-16 and binary files are not. For a UTF-8 file, the summary includes whether or not the file begins with the Unicode Byte Order Mark (U+FEFF). Any following data encountered that is not well-formed ASCII or UTF-8 Unicode is considered to be binary data; upon reading such data the input file is considered not to be a proper text file and the program exits with an error status.

The utfcheck program returns an exit status of EXIT_SUCCESS if the text file was well-formed, and EXIT_FAILURE otherwise.
