How to type O with Circumflex
To type O with Circumflex (ô), press Alt + 0244 on Windows, holding Alt while typing the digits on the numeric keypad, or press Option + I, O on Mac, or write ô in HTML. On any system you can copy it from this page, or enter its codepoint U+00F4 directly: Ctrl+Shift+U then 00f4 on Linux, or 00f4 then Alt+X in Microsoft Word.

Other accents symbols
ô 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 Ll, a lowercase letter. It has an uppercase counterpart and changes under case conversion. Its bidirectional class makes it left-to-right.
ô has a decomposed form: it can also be written as U+006F Latin Small Letter O, U+0302 Combining Circumflex Accent. The two look identical and are not equal as strings, which is why a search for a word containing ô sometimes fails against text that was typed on a different system. Everything on this site uses the single-codepoint (NFC) form shown here.
Its uppercase counterpart is Ô (U+00D4). They are separate codepoints, so a byte comparison treats them as different characters even though a case-insensitive search does not.
Typing ô without switching keyboard
ô is the letter O carrying a circumflex accent, and it is needed in French and Portuguese. 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 + I, let go, then press 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 + 6 into the same dead key. Add that layout once under Language and region, and ô costs two keystrokes from then on rather than four digits on a numeric keypad.
How O with Circumflex behaves in software
ô 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 ô arrives as ô
That is this exact character, undamaged: its two UTF-8 bytes C3 B4 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+00F4.
