Pedalling

b. 81

composition: Op. 35, Sonata in B♭ minor, Mvt II

 in GC (→GE)

No sign in FE (→EE)

..

The  sign was added in GC (→GE) probably by Chopin. It can be assumed that it indicates sustention of pedal throughout four bars.

b. 158

composition: Op. 35, Sonata in B♭ minor, Mvt II

 on 2nd beat in GC (→GE)

 on 1st beat in FE (→EE)

..

It is hard to state which of the sources guessed the sense of the notation of [A] more accurately. It is highly likely that even seeing the autograph, we would not be sure how to assign the  sign, as in the case of the lower placed notes, Chopin would often put these signs before the note and not under it, which sometimes resulted in ambiguities. In the discussed bar, both pedalling versions are possible; to the main text we adopt the less schematic version. The absence of  in GC is a patent oversight.
Similarly in bar 159.

composition: Op. 35, Sonata in B♭ minor, Mvt II

 on 2nd beat in GC (→GE)

 on 1st beat in FE (→EE)

..

It is not certain which pedalling is compatible with Chopin's intention. From the practical point of view, both are possible.

b. 160

composition: Op. 35, Sonata in B♭ minor, Mvt II

 on first beat in GC (→GE)

No sign in FE

 at the end of bar in EE

..

No  in FE is rather of an accidental nature, although the pedal can be sustained longer than it results from the notation of GC (→GE). It is confirmed by the  sign added in EE, which can come from Chopin (which does not mean that it was reproduced accurately – perhaps Chopin wrote it slightly earlier, e.g., on the 3rd beat of the bar).

b. 200

composition: Op. 35, Sonata in B♭ minor, Mvt II

 in GC (→GE) & FE

The absence of  is most probably an oversight of the engraver of EE.
