National letters in strings from ResourceBundle

[Brzezi]

Hi.

I`m writing program, in it I`m using strings received from .properties file
by ResourceBoundle, end if I put this strings into components like JLabel,
JButton, instead of national letters (in this case Polish letters) I see
'?'

I use NetBeans4.0 IDE, if I hardcode strings into source, everything is
good, without i'?', .properties files I edit in NetBeans too,

Do you have any idea how to solve it?


Pozdrawiam

Properties.load() want non-Latin-1 characters as \uxxxx escape codes.

See http://java.sun.com/j2se/1.5.0/docs/api/java/util/Properties.html#encoding

This looks like character encoding problem.

ResourceBundle is an abstract class, with two known subclasses. For a
resource bundle read from a .properties file, PropertiesResourceBunble is
used. The API for this class refers to ResourceBundle and Properties. It
also makes a special note of mentioning charcater encodings at:
http://java.sun.com/j2se/1.5.0/docs/api/java/util/Properties.html#encoding

A quote from that page:
"This format uses the ISO 8859-1 character encoding. Characters that cannot
be directly represented in this encoding can be written using Unicode
escapes; only a single 'u' character is allowed in an escape sequence.
The native2ascii tool can be used to convert property files to and from
other character encodings."

For more information on unicode escapes, see:
http://java.sun.com/docs/books/jls/second_edition/html/lexical.doc.html#100850

(a) Only use ISO Latin 1 characters in the properties files
(b) For other characters use the \u.... notation
(c) To avoid having to type all the \u stuff manually, use the
native2ascii tool that comes with the SDK and add it to your build system.
