-- Correct:
set @value = fn_n_decrypt_char([home phone], 0, 0, 1)

-- Wrong: this will decrypt the literal value "home phone"
set @value = fn_n_decrypt_char('home phone', 0, 0, 1)

-- Correct:
exec sp_n_encrypt_col [student table], [home phone], 1

-- Wrong: this will generate an error
exec sp_n_encrypt_col 'student table', 'home phone', 1

Tip: It is always ok to enclose table or column names in [brackets] even if they do not contain embedded spaces:

-- Both are correct:
exec sp_n_encrypt_col students, telephone, 1
exec sp_n_encrypt_col [students], [telephone], 1
