How to save Farsi text in csv file using python?

Question

I was trying to save my dataset in a CSV file with the following script:

with open(data_path+'Furough.csv', 'w',encoding="utf-8") as f0:
    df = pd.DataFrame(columns=['title','poem','year'])
    for f in onlyfiles:
        poem=[]
        title=""
        year=0
        with open(mypath+f,"r",encoding="utf-8") as f1:
            for line in f1:
                if line.__contains__("TIMESTAMP"):
                    year=int(line[12:15])
                    continue
                if line.__contains__('TITLE'):
                    title=line[7:]
                if line!="":
                    poem.append(line)
            df = df.append({
                            'title': title,
                            'poem':poem,
                            'year': int(float(year))
                            }, ignore_index=True)
            df.to_csv(f0, index=False,encoding='utf-8-sig')

but the result is confusing, write some unknown chars to CSV file instead of Farsi chars: Can anyone help me?

I want to write all these files in a CSV: example of what I have in one of them and want to write:

[V_START] بر پرده‌های درهم امیال سرکشم [HEM]
نقش عجیب چهرۀ یک ناشناس بود [V_END]
[V_START] نقشی ز چهره‌ای که چو می‌جستمش به شوق [HEM]
پیوسته می‌رمید و بمن رخ نمی‌نمود [V_END]

[V_START] یک شب نگاه خستۀ مردی به روی من [HEM]
لغزید و سست گشت و همان ‌جا خموش ماند [V_END]
[V_START] تا خواستم که بگسلم این رشتۀ نگاه [HEM]
قلبم تپید و باز مرا سوی او کشاند [V_END]

but result:

Answer 1

It's likely your file is correct and excel is opening it with another encoding.

Maybe inserting a utf-8 BOM could force excel to properly recognize the csv as utf-8:

import codecs

with open(data_path+'Furough.csv', 'w',encoding="utf-8") as f0:
    f0.write(codecs.BOM_UTF8)

    # rest of your code

Otherwise see this microsoft help page on how to open UTF-8 CSV file in Excel without mis-conversion ?
Basically going through the “Get Data From Text” dialog which allos to specify the encoding.

Answer 2

To add to Cimbali's answer, another method to add a UTF8 BOM is by using the encoding "utf-8-sig" instead of "utf-8", as it will automatically take care of it for you.
