Use of tab characters in indentation-sensitive code

I have found on a number of occasions that the use of tab characters in
indentation-sensitive code is a cause of compilation errors, on occasions
where I have opened the file with an editor which ap0plies a convention
other than 8 spaces for a tab. I fear that sooner or later, one of these
errors is going to manifest as a logic error.
I would suggest that, where code uses the indentation-scope feature of
Haskell, it would reduce the possibility for errors of all tabs were
replaced with a corresponding number of spaces.
I think that compilers should issue a warning when indentation that
determines the scope of a construct is found to contain tab characters.
