仲裁申请书申请人:额家的,女,汉族,身份证号码:3332324324525452426 住所:圣诞节啊客服经理撒打 has been converted to AFH a FA Fig A: REND . 2, DK, AGES: 3332324324525452426 FERT: PINTS RIAN 4 HEE 105 Bs ZSERBA: WWIII SS KEM. KAKA RIM. WA AHBL

so how to enable chinese OCR in tika ？

### Desired Solution you'd like

what paperless-ngx do as following ：

#      The default language to use for OCR. Set this to the language most of your
#      documents are written in.
PAPERLESS_OCR_LANGUAGE=eng+chi_sim

#      Additional languages to install for text recognition, separated by a whitespace.
#      Note that this is different from PAPERLESS_OCR_LANGUAGE (default=eng), which defines
#       the language used for OCR.
#    The container installs English, German, Italian, Spanish and French by default.
#     See https://packages.debian.org/search?keywords=tesseract-ocr-&searchon=names&suite=buster
#     for available languages.
