Ant compile: unclosed character literal

When I compile my web application using ant I get the following compiler message:

unclosed character literal

The line of offending code is:

protected char[] diacriticVowelsArray = { 'á', 'é', 'í', 'ó', 'ú' };

Wh开发者_JAVA百科at does the compiler message mean?

Java normally expects its source files to be encoded in UTF-8. Have you got your editor set up to save the source file using UTF-8 encoding? The problem is if you use a different encoding, then the Java compiler will be confused (since you're using characters that will be encoded differently between UTF-8 and other encodings) and be unable to decode your source.

It's also possible that your Java is set up to use a different encoding. In that case, try:

javac -encoding UTF8 YourSourceFile.java

---

Use UTF encoding for text files with your Java sources.

or

Use '\uCODE' where CODE is Unicode number for á, é etc. (like for 'á' you write '\u00E1').

You might need this:

It worked for me to use " instead of the ' char.

It also worked the javac -encoding UTF8 param as previously described. This means that the compiler did not used the UTF8 coding.
