String Viewer
Description
Is a feature available for non-retail PS3 models
Accesible from an icon at XMB category 
[Settings] > [String Viewer]
Its position in settings category is defined by the settings_order 0x13 in category_setting_plugin.sprx (In XMB is displayed as the last icon most at bottom of settings category)
The name of the icon is loaded from category_setting_plugin.rco
<Text name="msg_tool_string_viewer">String Viewer</Text>
The icon launches strviewer_plugin.sprx module
There are 4 "xml object pages" inside strviewer_plugin.rco that can be loaded by the .sprx (the samples below are a reduced version with only its name and the action triggered when onInit):
<Page name="page_strviewer_lang"... onInit="event:native:/OnInitStrViewerLang"... <Page name="page_strviewer_plugin"... onInit="event:native:/OnInitStrViewerPlugIn"... <Page name="page_strviewer_id"... onInit="event:native:/OnInitStrViewerID"... <Page name="page_strviewer"... onInit="event:native:/OnInitStrViewerDialog"...
String Viewer supports multilanguage. The page page_strviewer_lang contains a list of languages associated with letter codes, see: Talk:Languages
Speculation
Maybe is posible to make visible the icon in some PS3 models by using a Button Combo
Pre-retail firmwares
In old firmwares can be seen how string viewer was loaded
<View id="seg_string_viewer"> <Attributes> <Table key="StrViewer"> <Pair key="icon_rsc"><String>item_tex_ms_icon</String></Pair> <Pair key="title"><String>String Viewer</String></Pair> <Pair key="module_name"><String>strviewer_plugin</String></Pair> <Pair key="module_action"><String>0</String></Pair> </Table> </Attributes> <Items> <Item class="type:x-xmb/module-action" key="StrViewer" attr="StrViewer" /> </Items> </View>
When adding this entry in a modern firmware and clicking in the icon, appears an error message asking for strviewer_cnf in dev_usb000
The file in path usb000/strviewer/strviewer_cnf needs to follow this format:
Title = "Strviwer Pwned" path = "/strviewer/" file = "working_example"
And the loaded xml seems to be using the format inherited from the dev_flash/vsh/resource/silk/xai/widgets/informationboard/strings/|infob_<language>.xml where is required to follow this format:
<str id="msg_dtype_C">Lorem ipsum...</str><!--dtype="C"--> <str id="msg_dtype_E">Lorem ipsum...</str><!--dtype="E"--> <str id="msg_dtype_W">Lorem ipsum...</str><!--dtype="W"--> <str id="msg_dtype_R">Lorem ipsum...</str><!--dtype="R"--> <str id="msg_dtype_T">Lorem ipsum...</str><!--dtype="T"--> <str id="msg_dtype_N">This is a notification</str><!--dtype="N"--> <str id="msg_dtype_G">This is a botton notification </str><!--dtype="G"--> <str id="msg_dtype_I">This simple text was automatically repeated several times and also added many asterisks of its own</str<!--dtype="I"-->
The valid values for the <!--dtype="C"--> (C,E,W,R,T,N,G,I) are hardcoded inside strviewer_plugin.sprx
