minimal webapp

Hi there,

When I let tomcat/jasper compile the following tag file 

<%= "ü does not work" %> // bytes c3 bc

compiles into umlaut_tag.java in which the umlaut is doubly utf-8 encoded
like this:

      out.print( "ü does not work" ); // bytes c3 83 c2 bc

String literals in jsp files work just fine, so I'd like to rule out
errors in my encoding setup.

(Tomcat is running with LC_ALL=de_DE.UTF-8.)

I've attached a minimal webapp demonstrating that jsp is working, but the tag files are not.

Thanks for the report. I can confirm that this is a Tomcat bug.

Fixed in:
- 11.0.x for 11.0.0-M5 onwards
- 10.1.x for 10.1.8 onwards
-  9.0.x for  9.0.74 onwards
-  8.5.x for  8.5.88 onwards

It you want a short-term work-around, add a single space character after <%@tag and before the newline.
