Copy an app's localized title and text of menu items
String resource files are just plist files. In the terminal, use plutil -p to dump the contents of the file, which consists of maps of English keys to localized translations:

$ plutil -p /Applications/TextEdit.app/Contents/Resources/zh_CN.lproj/InfoPlist.strings


gives the output

{
  "Microsoft Word 2003 XML document" =&gt; "Word 2003 (.xml) 文稿"
  "Apple HTML document" =&gt; "网页 (.html)"
  "Unknown document" =&gt; "文稿"
  "Microsoft Word 97 document" =&gt; "Word 97 (.doc) 文稿"
  "CFBundleDisplayName" =&gt; "文本编辑"
  "NSRTFPboardType" =&gt; "多信息文本文稿"
  "Apple Web archive" =&gt; "网页归档文稿"
  "Microsoft Word 2007 document" =&gt; "Word 2007 (.docx) 文稿"
  "Apple SimpleText document" =&gt; "SimpleText 文稿"
  "NSRTFDPboardType" =&gt; "带附件的多信息文本文稿"
  "NSStringPboardType" =&gt; "纯文本文稿"
  "OpenDocument Text document" =&gt; "OpenDocument 文本 (.odt) 文稿"
  "NSHumanReadableCopyright" =&gt; "Copyright © 1995-2016 Apple Inc.
保留一切权利。"
  "CFBundleName" =&gt; "文本编辑"
}


(BTW, the title of the app is contained in CFBundleDisplayName and CFBundleName).
