We are using oracle database server on which encoding is set to: WE8ISO8859P1

SELECT * FROM NLS_DATABASE_PARAMETERS WHERE PARAMETER = 'NLS_CHARACTERSET';
NLS_CHARACTERSET WE8ISO8859P1

Encoding on db cannot be changed to UTF-8 because same db is used for other applications that will get impacted because of this change.

With default behavior of JIRA if i enter double quotes “ or ”, they get converted into question mark ?

Since db is using this char set, we want to change JIRA to support same char set, to achieve this we have made change in following places:
1. JIRA DB: using this query
update propertystring set propertyvalue = 'ISO-8859-1' where id in (select id from propertyentry where property_key='webwork.i18n.encoding');

2. JIRA start up file (setenv.sh), added following line in jvm arguments
-Dfile.encoding=ISO-8859-1

3. Tomcat's conf/server.xml added encoding
URIEncoding="ISO-8859-1"

After these changes and bouncing JIRA, i could see change reflected in my browser and could see encoding is chnaged from UTF-8 to ISSO-8859-1.. but the problem of quotes getting converted to question mark is still there..

can you pls look into this and let me know what should be solution for this..
