Search form error with unicode character in linux

[moviefuns]

Hello.
I've deployed piggydb with tomcat 8.5.3 on alpine linux 3.9. Everything is fine but some problem on search text form. When I input unicode characters in search form, in post result pages the keyword was replaced by question marks.
Followed many instructions I've add utf-8 encoding support in tomcat conf files, server.xml and web.xml, as bellow.

server.xml:
"<connector ..... URIEncoding="UTF-8" .... >"

web.xml
uncomment " setCharacterEncodingFilter ... " section and
"setCharacterEncodingFilter ... " section.

But with no luck, when I input unicode characters in search form, the result page still got question mark which should be the unicode characters.
Could anyone help me, please?

I had encountered similar problems, and I recommend using winstone.jar instead of tomcat. the command line for your reference:

java -jar winstone.jar --warfile=piggydb.war \
     --httpsListenAddress=0.0.0.0 --httpsPort=443 \
     --httpPort=-1 --ajp13Port=-1 \
     --httpsKeyStore=your_keystore_name.jks --httpsKeyStorePassword=your_keystore_password

• the winstone.jar version I used is 1.7.0 - url
• the md5 checksum is - 9ddcffb6158cee6278f797076c644560

Thank you. Try winstone.jar later.

UPDATE:
Awesome!
Winstone.jar works!
Thank you pimgeek!
