I am a beginner for android applications and I met a serious problem

[Andy Shair]

I joined a app development competition and I wanna use tesseract to read words for my project.

When I tried to use the tesseract, I noticed all the words it read is "Mojibake" and it cannot function well.

Then I checked the tessdata - eng.traineddata , and I found that the things inside are also "Mojibake".

I don't know why and the deadline is arriving...

Can someone help?
