Same problem on ubuntu 15.04 64 bit up to date with libre office Version: 4.4.6.3, Build ID: 40m0 (Build:3), Locale : fr_FR.UTF-8.
My document is a fresh one and behavior is exactly the same (some char in title disappear).
Zooming in/ou/ editing the title make the missing characters back for a short period of time.
Update to LO 5.x is not possible for me (pro computer with limited update options).
