How can I put UTF8 value to web.xml?

Question

I'm thinking to put some UTF-8 words into web.xml as env-entry-value, but somehow that will cause my war become not deployable to my server. A case of my setting that causes deployment failure look like below.

<env-entry>
    <description>Msg text</description>
    <env-entry-name>Msg_Text</env-entry-name>
    <env-entry-type>java.lang.String</env-entry-type>
    <env-entry-value>兔子</env-entry-value>
  </env-entry>

error msgs

Can anyone teach me how to do it?

======Update======

Tried that with semi-colon again, &#53F0;, then it got other error

If I fill it with normal ascii characters, it works good. Do I missed anything else on that?

This is most likely an encoding problem which cannot be analyzed without additional information if you cannot open the xml file in a modern browser . I would suggest using the “hex;” notation (where hex is the Unicode value for that character, repeat for each) — Thorbjørn Ravn Andersen, Jun 10 '21 at 09:31
@ThorbjørnRavnAndersen tried it with `5F0`, and jboss is still not happy about it. =/ — Kaninchen, Jun 10 '21 at 19:49
The obvious question is: Have you have got as the first line in your web.xml file? — Jonathan, Jun 10 '21 at 20:17
@Jonathan Yeah, it does. Ain't it suppose to be part of default value when you create a web project using modern IDE lke eclipse or intellij? eclipse seems like it will do it at least — Kaninchen, Jun 11 '21 at 03:24

web.xml must contain <?xml version="1.0" encoding="UTF-8"?> or <?xml version="1.0"?>: any other encoding would corrupt Unicode text content.
Edit web.xml in UTF-8; a programmer's editor like NotePad++ would do.
For hexadecimal do not forget the x: 台.

OMG! that little `x` is the last puzzle! thanks! – Kaninchen Jun 11 '21 at 07:38
But it doesn't explain why your UTF-8 char wasn't accepted by JBoss ... – Jonathan Jun 13 '21 at 01:41
@Jonathan is right, hence my first two points on encoding. A pity that part is left unsolved. – Joop Eggen Jun 13 '21 at 20:13
My bad, I forgot the x. – Thorbjørn Ravn Andersen Jun 15 '21 at 15:15
