ij.unicodeEscape

Function

Set this property to on to allow unicode escape sequences as input characters. By default, ij accepts unicode characters, not unicode escape characters.

If set to on, enter unicode symbols using unicode escape sequences (hexadecimal codes).

Syntax

ij.unicodeEscape= { onoff }

Examples

The following command line specifies to run ij using the Japanese locale (territory=ja), in Japanese Latin Kanji mixed encoding (codeset=Cp939), allowing Unicode escape sequences (unicodeEscape=on):

java -Dderby.ui.territory=ja -Dderby.ui.codeset=Cp939 
  -Dij.unicodeEscape=on -Dij.protocol=jdbc:derby:
