Well, if you meant "if the original string was ASCII, can I convert back to 
ASCII", the answer is "yes" :-)

If the string contains non-ASCII characters:

toLatin1() - if the characters are in Latin 1, then the string is safe; if 
not, they will be replaced by a question mark

toAscii() - in Qt 5, the behaviour is undefined; in Qt 4, it depends on the 
codec set by setCodecForCStrings. The default codec is Latin 1.
