About the accented letter J
The letter J carries 5 accented forms in the lists we cover here: 3 lowercase and 2 uppercase. These range from everyday characters like ĵ ǰ to far rarer variants you will mostly meet in specialist or historical texts. Each one has its own Windows Alt code, which is exactly what this quiz drills you on.
Across the world's languages, J appears with the circumflex (ĵ) and the caron (ǰ), among other marks. A diacritic is not decoration: it can change how the letter sounds, shift where the stress falls, or turn one word into a completely different one. Recognising each mark, and knowing the Alt code that produces it, is what separates a quick guess from real fluency.
How to type accented J with Alt codes
On Windows, hold down the Alt key, type the number on the numeric keypad (with Num Lock on), then release Alt. For example, Alt + 309 produces ĵ. Codes shown with a leading zero, such as 0193, need that zero typed too. On a laptop without a numeric keypad, turn on the on-screen keyboard or use your operating system's character viewer. Study the full list below, then put yourself to the test.
