You can check whether there is not a non-breaking space between the software name and the version number with this search expression:
Search settings: Regex Mode, Powersearch (Ctrl+P)
\x00a0 stands for non-breaking space (hexadecimal code).
Note that you should replace Software with the actual program name and that the dot (
.) in the version number must be escaped with a backslash (
\). If not, the dot means any character in Regex.
With these search settings, Xbench will display all segments that contain Software + whitespace + VersionNumber in the source text and do not have Software + non-breaking space + VersionNumber in target.
