The issue occurs because of a specific font set on the computer when CJK language is used for recognition.

The possible solutions are the following:

• Change the set of fonts, which are used during document synthesis, having removed specified Arial Unicode MS and having set other fonts with CJK support e.g. MS Mincho, MS PMincho. To do this please set the fonts using ISynthesisParamsForDocument::FontSet object.
• If you recognize non-CJK text, remove CJK language from the list of recognition languages.
