I want to add a new language (Thai) in my Liferay DXP 7.2 but can't able to add. I have followed below steps:
Added mapping to web.xml file (LIFERAY_HOME\tomcat-<version>\webapps\ROOT\WEB-INF
)
<servlet-mapping>
<servlet-name>I18n Servlet</servlet-name>
<url-pattern>/th/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>I18n Servlet</servlet-name>
<url-pattern>/th-TH/*</url-pattern>
</servlet-mapping>
Added URL pattern to web.xml file (LIFERAY_HOME\tomcat-<version>\webapps\ROOT\WEB-INF
)
<url-pattern>/th/c/portal/protected</url-pattern>
<url-pattern>/th-TH/c/portal/protected</url-pattern>
I found 4 portal-ext.properties files (PROJECT_NAME\Config\local\portal-ext.properties, PROJECT_NAME\Config\dev\portal-ext.properties, PROJECT_NAME\Config\uat\portal-ext.properties, PROJECT_NAME\Config\prod\portal-ext.properties), added following locales in every files.
locales=th,ar_SA,eu_ES,bg_BG,ca_AD,ca_ES,zh_CN,en,en_US,th_TH
Restarted the tomcat server but in Portal UI: Configuration > Settings > Languages it's still not showing on Available language's section

Probably one more step is pending which is icon and language_<langCode>.properties
files related changes. But still after completing the above steps I should able to find newly added language on settings available language list page on UI.
After all steps you followed, new language should be displayed in "Control Panel" => "Configuration" => "Instance Settings" => "Localization" in "available" column.
You have to add it at instance level before adding it to a existing site.
