Although it's awkward, you should be able to do what you want by "escaping" the quotation marks surrounding the level name; the following (untested) should work:

trust <- recode(Poland$SN35B, " 'Strongly Agree' = 1; 'Agree' = 2; 'Neither Agree nor Disagree' = 3; 'Disagree' = 4; 'Strongly Disagree' = 5; \"Can't choose\" = 6; else=NA")

I hope this helps,
 John
