Java language specification (#7.2.1 Storing Packages in a File System) says:

"A package name component or class name might contain a character that
cannot correctly appear in a host file system's ordinary directory
name, such as a Unicode character on a system that allows only ASCII
characters in file names. As a convention, the character can be escaped
by using, say, the @ character followed by four hexadecimal digits
giving the numeric value of the character, as in the \\uxxxx escape
(3.3), so that the package name:

children.activities.crafts.papierM\\u00e2ch\\u00e9

which can also be written using full Unicode as:

children.activities.crafts.papierMâché

might be mapped to the directory name:

children/activities/crafts/papierM@00e2ch@00e9

If the @ character is not a valid character in a file name for some
given host file system, then some other character that is not valid in
a Java identifier could be used instead."

The example below is compiled successfully and pkgs008.class is placed to the directory

javasoft/sqe/tests/lang/pkgs007/pkgs00701é

while fully qualified class name in pkgs00701.class is

javasoft/sqe/tests/lang/pkgs007/pkgs00701é/pkgs00701

So the compiled class cannot be found for execution:

>javac -d . pkgs00701.java
> java javasoft.sqe.tests.lang.pkgs007.pkgs00701é.pkgs00701
Can't find class javasoft.sqe.tests.lang.pkgs007.pkgs00701é.pkgs00701
