As an additional data gathering, could you test if it's the same on wily
images ie ubuntu-touch/devel/ubuntu ? wily has Qt 5.4.2 so additional
fixes compared to vivid's Qt 5.4.1. If the problem would be fixed on
wily, we could try to find out the exact fix and backport.

Is it possible to somehow reproduce this on desktop, for example a QML
file that tries to display the same characters?

It'd be best to be able to submit a bug report to upstream bug tracker
https://bugreports.qt.io/ , but they'd need a test case they can test
themselves with plain Qt without Ubuntu additions.

Title:
  Missing Chinese word rendering in title of qml Page render, when using
  GRID_UNIT_PX=23

Status in qtdeclarative-opensource-src package in Ubuntu:
  New

Bug description:
  If switch GRID_UNIT_PX to 23 in arael, there will be one Chinese word
  in title missing randomly.

  The default was 40gu, and it works fine. But if switching to
  50gu/23px, one of the 4 words in system-settings will be missed to
  render.
