I don't really find a right method to fix this because the
char-displayable-p function seems not to be accurate in many
cases. There was a discussion about this before, but there was not a
final agreement I think. And from the char-displayable-p documentation:
```
On a multi-font display, the test is only whether there is an
appropriate font from the selected frame's fontset to display
CHAR's charset in general. Since fonts may be specified on a
per-character basis, this may not be accurate.
```
Any suggestion here?
Once we have the details I requested from Robert.

How come '|' is displayed as '['? What does Emacs show in *Help* if
you (Robert) go to that character and type "C-u C-x ="?
