#310 closed bug (wontfix)

Singular terminates after input say "x³" instead of "x^3"

Reported by: anonymous Owned by: somebody
Priority: minor Milestone: 3-1-3 and higher
Component: dontKnow Version: 3-1-2
Keywords: Cc:


Using Ubuntu 10.04, if you type 'x'+caret+'3' the console writes it as "x³", which Singular does not accept as input.

This would be no problem in of itself, but Singular immediately terminates after the error message.

   ? error occurred in or before STDIN line 2: `poly p=x1³;`
   ? expected poly-expression. type 'help poly;'
   ? last reserved name was `poly`
Auf Wiedersehen.

P.S.: please imagine between the two lines several definitions of very complicated polynomials, and many time-consuming calculations (e.g. computing certain groebner bases to solve a sudoku), whose lengthy results need now to be copy-pasted.

Resolution: wontfix
Status: newclosed

resolved as "wontfix": users have to be careful what keys to use for input; some key may result internally in control sequences that may even cause SINGULAR to terminate (as in the example at hand)
