推荐答案

从tesseract 3.02开始，可以为-l参数指定多种语言.

Since tesseract 3.02 it is possible to specify multiple languages for the -l parameter.

-l lang使用的语言.如果未指定，则假定为英语.可以指定多种语言，用加号分隔. Tesseract使用3个字符的ISO 639-2语言代码.

-l lang The language to use. If none is specified, English is assumed. Multiple languages may be specified, separated by plus characters. Tesseract uses 3-character ISO 639-2 language codes.
