One of the AutoCorrect options is to automatically capitalize days of
the week. It works, but you may get more than you bargained for. If
you happen to type the words for days of the week in a foreign
language, AutoCorrect will capitalize them, even though there are no
(visible) AutoCorrect entries for them, and even though automatic
language recognition is off.
For example, it will capitalize Turkish day names; Pazar (Market Day,
Sunday), Pazartesi (After Market Day, Monday), Sali (Tuesday),
Çarsamba (Four days after Sabbath, Wednesday), Persembe (Five days
after Sabbath, Thursday), Cuma (Reunion Day, Friday), Cumartesi (After
Reunion Day, Saturday). (The "s" in Çarsamba and Persembe and the "C"
in Çarsamba should have a cedille under them; this may not come
through in all newreaders.)
It will also capitalize day names in German, and probably in many
other languages. It will not capitalize French day names, because that
is not the custom in France. If you happen to know day names in other
languages, you can amuse yourself by trying them out.
This is probably a bug caused by a feature. If Microsoft had just put
the day names in the default AutoCorrect lists for each language, this
problem would not occur. When they decided to have a separate check
box for capitalizing day names, some unknown programmer took the easy
way out and just made one big (hidden) list instead of doing it
per-language.
