TOC Macro does not work for Japanese headings ....

he TOC macro does not work correctly for Japanese headings in Confluence 4.0.3.

For example,

{toc}

h1. 山田
text
text
text
text
text
h1. 島田
text
text
text
text
text
h1. 熊田
text
text
text
text
text
{toc}

creates following table of content.

山田
島田
熊田

However, clicking any of the link always points to the first heading.

The actor point always becomes '~'
