Saving special characters in properties file

Question

I have property with string that contains some special characters. After I save it to properties file I have:

BB\u0161BB=0

I don't like character represented with \š . Why it can't save like character I see it on the screen and type from keyboard?

UPD What is the easiest way to read ini-file architecture file that contains special character?

Answer 1

That's how Properties files are defined to behave. Any other system is likely to use UTF-8 which might not be readable either.

As your character is outside the range of an ISO-8859-1 encoding, it has to use unicode instead.

Answer 2

You can't. From javadoc:

...the input/output stream is encoded in ISO 8859-1 character encoding. Characters that cannot be directly represented in this encoding can be written using Unicode escapes as defined in section 3.3 of The Java™ Language Specification; only a single 'u' character is allowed in an escape sequence.

Please refer to this How to use UTF-8 in resource properties with ResourceBundle

Answer 3

属性文件是ISO-8859-1编码的，因此该集合之外的字符需要进行\\uXXXX转义。

Answer 4

You can!

Encode your file in unicode (UTF-8, for instance) using another application (Notepad++ is nice, for instance) and read your properties file like this:

File file = ... ;
Properties properties = new Properties();
try (FileInputStream in = new FileInputStream(file);
     Reader reader = new InputStreamReader(in, StandardCharsets.UTF_8)) {
  properties.load(reader);
}
// use properties

There you go, properties file in any charset that you can read and use.
