This defect (CLRT-80925) is also known as DE29596.
DE30535/CLRT-81494 is heavily related to this so both were treated as the same defect and fixed as a unit.
You can find that this has been fixed here:
Resolved Defects - CA PPM - 15.2 - CA Technologies Documentation
as:
CLRT-81494, DE30535, DE30876, DE31582 (S3): LONG HYPHEN IS REMOVED IN MSP (Issues saving projects back to Microsoft Project)
Even though that this states a specific case, this was involving many different issues that were caused by the presense of some special characters. As mentioned earlier, these were all treated as a single issue (as they shared the root cause) and can appear either on load or on save, despite the description, as it is based on specific steps to reproduce for a given defect.
The fixes have been backported to 14.3.0.10, 14.4.0.6 and 15.1.0.3 as well.
Hope that this helps you.
