Bug with StringEscapeUtilities' escapeHTML/unescapeHTML for certain characters

[Burt Leung]

Hello,

I recently used the StringEscapeUtilities to encode/decode a character
into its equivalent HTML entity. While I haven't used it much I do
notice that a couple cases in particular seem "wrong".

case1: StringEscapeUtils.escapeHtml4("ä")
This appears to give "ã". This should actually be "ä".

case2: StringEscapeUtils.escapeHtml4("å");
This gives "&aring" but should actually be "ã".

Using the unescape functional also gives the (incorrect) reverse results.

Is this an actual bug or am I missing something?

Thanks,
Burt
