How to type Capital O with Diaeresis
To type Capital O with Diaeresis (Ö), press Alt + 0214 on Windows, holding Alt while typing the digits on the numeric keypad, or press Option + U, Shift + O on Mac, or write Ö in HTML. On any system you can copy it from this page, or enter its codepoint U+00D6 directly: Ctrl+Shift+U then 00d6 on Linux, or 00d6 then Alt+X in Microsoft Word.

Other accents symbols
Ö lives in the Latin-1 Supplement block (U+0080-U+00FF), the accented letters and common signs Western European languages needed. Within Unicode it is classified as Lu, an uppercase letter. It has a lowercase counterpart and changes under case conversion. Its bidirectional class makes it left-to-right.
Ö has a decomposed form: it can also be written as U+004F Latin Capital Letter O, U+0308 Combining Diaeresis. The two look identical and are not equal as strings, which is why a search for a word containing Ö sometimes fails against text that was typed on a different system. Everything on this site uses the single-codepoint (NFC) form shown here.
Its lowercase counterpart is ö (U+00F6). They are separate codepoints, so a byte comparison treats them as different characters even though a case-insensitive search does not.
Typing Ö without switching keyboard
Ö is the letter O carrying a diaeresis, and it is needed in French, Spanish and German. It is one character rather than two: a spell checker treats it as a letter of those alphabets, not as O with something added.
Both of the routes worth knowing compose the letter rather than looking it up. On a Mac press Option + U, let go, then press Shift and O: nothing appears until the second key, because the first one is a dead key waiting for a letter to sit under. On Windows the same idea needs the United States-International layout, which turns Shift + apostrophe into the same dead key. Add that layout once under Language and region, and Ö costs two keystrokes from then on rather than four digits on a numeric keypad.
How Capital O with Diaeresis behaves in software
Ö takes one column in a terminal. It is a left-to-right character, so it holds that direction even inside a right-to-left paragraph.

If Ö arrives as Ö
That is this exact character, undamaged: its two UTF-8 bytes C3 96 are being read one at a time as Windows-1252. The Latin-1 range is where this happens most, because it is the range every legacy system thought it already handled. Nothing is lost, and retyping will not help: the fix is at the reading end, which has to be told the text is UTF-8. An empty rectangle is the opposite complaint, and means the encoding is right and the font has no glyph for U+00D6.
