>Description:
-gnaty only permits 80 characters per line. However, if those characters are encoded in UTF-8, they are miscounted, and shorter lines are rejected. The Cherokee_String line in the attached file is 71 characters long, but 99 bytes long, and is rejected.
>How-To-Repeat:
Run gnatmake -gnaty test_strings.ads. It will return a "(style) This line is too long." error, when in fact this line is not too long.
