With certain characters a loop inside TQTextEngine::shape() could
repeat forever because some script engines were requesting more memory
because of a mistake.
In particular this were observed with at least letters "ई" (U+0908,
DEVANAGARI LETTER II) and "ༀ" (U+0F00, TIBETAN SYLLABLE OM).
The problem was already solved in Qt somewhere between last Qt3 release
and first Qt4. But due to no public VCS is available it's impossible to
pinpoint an exact commit. This patch is heavily based on the Qt-4.3.5
code.

If the selected font supports the required characters, the text will be displayed correctly.
If the selected font does not support such characters, empty boxes will be displayed in place of the expected text.
Part of the code changes comes from Qt4 code.
