描述问题 Describe the problem

I have tesseract installed with additional languages not including Chinese.
In the log file I see tesseract.go:126: no chi_* tesseract lang found, but tesseract is still enabled.
As soon as any images are fed to the OCR engine, the result is a failure with error code 0xc0000005.

期待的结果 Expected result

I would like that the OCR engine correctly processes all my images, using all my installed language packs.
This should be independent from the precise language packs that I decide to install.

更多信息 More information

In source file kernel/util/tesseract.go, inside the function initTesseract(), the variable TesseractLangs is only populated with languages when both eng and chi* are found in the installed list of languages, otherwise that variable stays empty and creates a bad command line (-l ) that crashes tesseract with error code 0xc0000005, "access violation".

I do not have any chi* language installed with my version of tesseract, and that causes this problem.

Suggestion: please make the list of languages to pass to tesseract configurable, with all languages enabled by default (not just eng and chi*).
