Of course now I found it out - short after I spend time to post the
question :-)
The related HTML code is defined by the template file in trac/
templates/layout.html (which is in my case in /usr/lib/python2.5/site-
packages/Trac-0.11.1-py2.5.egg/),
from line 23:
<script py:for="script in chrome.scripts"
type="${script.type}" src="${script.href}">${script.content}</
script>
After I changed it to:
<script py:for="script in chrome.scripts" charset="$
{script.charset}"
type="${script.type}" src="${script.href}">${script.content}</
script>
my test code started to work.
Still this doesn't do my trac macro any good, and I don't like to
implement a template provider just for this.
I might just file an enhancement ticket - at least the charset should
be user definable.
