\section2 8-bit Character Comparisons
In QByteArray, the notion of uppercase and lowercase and of which
character is greater than or less than another character is
locale dependent. This affects functions that support a case
character is greater than or less than another character is done
in the Latin-1 locale. This affects functions that support a case
insensitive option or that compare or lowercase or uppercase
their arguments. Case insensitive operations and comparisons will
be accurate if both strings contain only ASCII characters. (If \c
$LC_CTYPE is set, most Unix systems do "the right thing".)
be accurate if both strings contain only Latin-1 characters.
Functions that this affects include contains(), indexOf(),
lastIndexOf(), operator<(), operator<=(), operator>(),
operator>=(), isLower(), isUpper(), toLower() and toUpper().
