Output Encoding Format
In order to output data correctly according to the specified encoding format, you
need to specify the output encoding format, such as simplified Chinese output in
Notepad / excel, configuring the format into GBK . In word, configuring the format
into UNICODE.
When the output encoding format is English/Latin-1, the output mode of the USB
keyboard is affected by the virtual keyboard function on/off, When the output
encoding format is GBK / UNICODE , the output mode of the USB keyboard is
forced to be the virtual keyboard output.
