I can't reproduce that problem on GNU/Linux system.

This is very strange.  243 is the byte code of that raw-byte
character #x3ffff3.  But, usually the log should say that
the character code is #x3ffff3, And, it says that the
character has `charset' text property `iso-8859-1'.  But,
describe-char doesn't show that property.

Is it a Windows specific problem?
