I am Korean, but I am not good at English, so I use Google Translator to write.
Even if the context is not right, please ask for your understanding.
When using Find (Ctrl + F), "PDF XChage Editor" of the End-User version can input double(multi)-byte characters, but "PDF-XChage Editor SDK" for developers does not input double-byte characters.
Tests have been done from versions "6.0.321.0" to "7.0.325.1", but they are the same.
Search (Ctrl + Shift + F) works fine.
Please check the attached video for more details.
I would be very grateful if you could give me a solution.
Thank you for reading.
Happiness will be with you.
