Character encoding according to page indication

Question

Hello.
I'm not sure this forum is the better one to post such a question. Perhaps the Tomcat list could be another good place... So if someone has a better idea, it's welcome...
I've tested how the JSP 2.0 processor generates, or not, character encodings, using a recent Tomcat 5.5.
In a same page, with a content type defined in "text/xml" using a charset "UTF-8", i can use 3 equivalent forms to write out a character.
1) the old scriptlet expression : <%=myAttribute%>2) The new EL form, directly put in the page body : ${myAttribute}3) The jstl solution : <c:out value="${myAttribute}"/>And the winner is :
In (1) and (2), no special processing is done, and if my string contains any '<' , the generated document is mal formed... too bad !
In (3), with the default use for encoding, the possible '<' or any other special character are converted to the correct xml entity... and the document wins !
So... my question : in there a particular part of the (servlet + jsp + taglib + jstl + el) specifications that clearly explains how characters should or must be encoded by the server, and when this is the application responsability...
Thanks for your help...

If you want the list to be automatically updated as you edit, Obi-wan's 27 grep styles along with 27 swatches is the way to go.
You could also do it with a script which would require less setup—the grep approach would need a paragraph style with 27 grep rules linked to 27 character styles using 27 swatches.
This AppleScript (OSX only) picks up the first character of the paragraph and colors the paragraph text with a swatch named the same. So this short example uses uppercase A, B, C named swatches to color corresponding paragraphs starting with the same letter:
tell application "Adobe InDesign CS6"
    --make sure there's a selection and get the text and its frame
    try
        set c to {insertion point, character, word, line, paragraph}
        if class of selection is in c then
            set t to parent of selection
        else if class of selection is text frame then
            set t to parent story of selection
        end if
    on error
        display dialog "Please select some text"
        return
    end try
    --get all of the story paragraphs
    set p to object reference of every paragraph of t
    --color each paragraph with the swatch that's named with the paragraph's first letter
    repeat with x in p
        set c to character 1 of x as string
        set s to (every swatch of active document whose name is c)
        try
            set fill color of every character of x to item 1 of s
        end try
    end repeat
end tell
