• 符号ふごう — symbol; code; sign
• 音符おんぷ — musical note; musical symbol
• 切符きっぷ — ticket (for train, bus, etc.)
• 割符わりふ — tally or token used to divide shares

With the bamboo crown on top, 符 originally suggested bamboo slips that matched up as a pair — a kind of physical token or tally. From there it came to mean symbols, codes, and tickets: little marks that stand in for something larger.
