The main encoding issue here is, for some languages like Hebrew, Chinese, Arabic, etc there might get the chance of appearing as question marks instead of actual specific text. This issue might be due to different cases.

1. Sometimes the serverside rendering language like jsp, gsp pages might cause the issue we can use the following tag in those pages.

2. We might get the issue due to database data where we don't set the configugre the utf-8 encoding. To resolve the issue we can set the jdbc connection url as follows:

Make sure to change the actual database instead of [database_name].

4. If we are using hibernate then better to configure the settings as

5. If we are using build tools like Jenkins for deployment we need to configure the encoding In Jenkins: we can create a global variable and set encoding config as below:
