You can specify Unicode (non-ASCII) characters in VMware Tanzu GemFire property files by using a \uXXXX escape sequence.
For a supplementary character, you need two escape sequences, one for each of the two UTF-16 code units. The XXXX denotes the 4 hexadecimal digits for the value of the UTF-16 code unit. For example, a properties file might have the following entries:
s1=hello there
s2=\u3053\u3093\u306b\u3061\u306f
In gemfire.properties, you might write the following to indicate the desired property definition of log-file=myß.log.:
log-file=my\u00df.log
If you have edited and saved the file in a non-ASCII encoding, you can convert it to ASCII with the native2ascii tool included in your Oracle Java distribution. For example, you might want to do this when editing a properties file in Shift_JIS, a popular Japanese encoding.
For more information about internationalization in Java, see Java Internationalization in the Oracle Java documentation.
