TASK DESCRIPTION
  With Qt5.11, we got <http://blog.qt.io/blog/2018/05/22/qt-5-11-released/> full \
Unicode support including isolation[1] characters that are useful in bidirectional \
text.  
  Knowing the fact how bidi text is hard to get right (Check 1 \
<https://phabricator.kde.org/R7:5bc9e0ac69072e2f6fcb8be56d693c428994f4b9>/1.5 \
<https://phabricator.kde.org/R7:8384d546baa8981351bdfcc8f9e1da2c213e3812> and 2 \
<https://github.com/lxqt/pcmanfm-qt>), I would like to discuss if we should enclose \
every placeholder used in KI18n with the two isolation characters FSI (u2068, First \
Strong Isolate) and PDI (u2069, Pop Directional Isolate) by default. This makes it \
much more easier for programs to support proper bidi text without a lot of work.  The \
downside of this is that apps running older version of Qt may get the text \
misrendered, and copying text to apps that doesn't support Unicode properly will \
cause issues.  
  Ideas?
  
  [1] Isolation is a way to seperate a specific chunk of text, detecting it's \
direction, getting the order correct and readding it to the actual text.  Example:
  Arabic string has a dot at start and an underscore at end: `_CIBARA.`
  Without the isolation it will show as: `This is an .CIBARA_ text.`
  With the isolation: `This is an _CIBARA. text.`
