我有一个列表（见下文），我希望将列表中包含Unicode字符（例如，'①'、'②'、''）的任何元素作为'category' JSON元素内的键/值对，并将列表中每个Unicode元素之间的以下元素作为'codes' JSON嵌套分组内的键/值对。
我有什么列表：

['①', 'Type of Care']
['SA', 'Substance use treatment']
['DT', 'Detoxification']
['HH', 'Transitional housing, halfway house, or sober home']
['SUMH', 'Treatment for co-occurring serious mental health illness/serious emotional disturbance and substance use disorders']
['②', 'Telemedicine']
['TELE', 'Telemedicine/telehealth']
['③', 'Service Settings (e.g., Outpatient, Residential, Inpatient, etc.)']
['HI', 'Hospital inpatient']
['OP', 'Outpatient']
['RES', 'Residential']
['HID', 'Hospital inpatient detoxification']
['HIT', 'Hospital inpatient treatment']
['OD', 'Outpatient detoxification']
['ODT', 'Outpatient day treatment or partial hospitalization']
['OIT', 'Intensive outpatient treatment']
['ORT', 'Regular outpatient treatment']
['RD', 'Residential detoxification']
['RL', 'Long-term residential']
['RS', 'Short-term residential']
['⑰', 'Assessment/Pre-treatment']
['CMHA', 'Comprehensive mental health assessment']
['CSAA', 'Comprehensive substance use assessment']
['ISC', 'Interim services for clients']
['OPC', 'Outreach to persons in the community']
['㉖', 'Facility Smoking Policy']
['SMON', 'Smoking not permitted']
['SMOP', 'Smoking permitted without restriction']
['SMPD', 'Smoking permitted in designated area']

我想创建的键/值对JSON：
