Unicharset_extractor meet ICU ERROR

[yang3...@gmail.com]

Environment

• Tesseract Version: <4.00>
• Platform: <Windows 64>

Current Behavior:

C:\Users\Jerry\Desktop\新建文件夹>unicharset_extractor chi_my.font.exp0.box
Extracting unicharset from box file chi_my.font.exp0.box
ICU ERROR: U_FILE_ACCESS_ERROR

But I find this will be solved by use [tesseract-ocr-setup-4.00.00dev.exe] . It will occur by use [tesseract-ocr-w64-setup-v4.0.0-beta.1.20180414.exe]
