    _______________________________________________________

Details:

If a java method expects a 'char' input (i.e. a 'java char' type, not an
octave 'char'), it is impossible to call it with valid input.

Example:


dfs = javaObject ( 'java.text.DecimalFormatSymbols' )
dfs.setDecimalSeparator( '.' )


I assume this is because octave treats '.' as a string and passes it to java
as a string object? Or something along those lines?

There are a couple of other bugs in the bug tracker here involving java and
chars, but these seem to mostly relate to conversions from java outputs, not
the inability to pass a 'java char value'.
