Yes, it does help.  The error is gone.

Exactly, and here I'd say it is definitively not the right behavior
because because both chars have a separate meaning (buffer writable?
and buffer modified?) and help-echo which aren't accessible anymore.

I don't know how to cope with such situations.  Maybe composition should
only consider strings with equal text properties.  Or, as you already
said, there should be some text property inhibiting composition which
the mode-line could use.
