Morphology
The meaning is directly compositional: 'alphanumeric' denotes letters and digits and 'characters' denotes symbols, so together they mean symbols made of letters and numbers. This is a standard, productively formed technical phrase that a B1 learner who knows both constituents would readily understand.
Etymology
The term alphanumeric characters comes from joining alpha, meaning letters, and numeric, meaning numbers, so it simply refers to characters that are 'letters and numbers' rather than other symbols.
