5.1.3 Files With Non-Graphic Characters

Four ACATS test files contain ASCII non-graphic (control) characters that may be lost or corrupted in the file transfer and decompression process. The user must ensure that the proper characters are restored as necessary.

There are also a number of ACATS test files provided in UTF-8 format. These files have an .au file extension. The user must take care that any processing tools do not corrupt UTF-8 files. (This would be unusual: it is most likely if a tool does not recognize UTF-8 formatted files and also modifies Latin-1 characters with codes larger than 127.)

The following paragraphs describe the four tests with ASCII non-graphic characters.
