That's the problem: the default case-table in Turkish locales will
fail case-insensitive search for ASCII strings.  Try this:

  emacs -Q
  M-x set-language-environment RET Turkish RET

Then type "PROPERTIES" into *scratch*, go to its beginning, and type
M-l.  You will see "propertıes".

Yes (except that Isearch has some heuristics regarding letter-case
when invoked interactively).  After set-language-environment to
Turkish, type "PROPERTIES", go to the beginning of the word you typed,
and do

   M-: (search-forward "i") RET

You will see that it fails.  Now reset language-environment to English
and repeat the same search: it will now succeed.
