I need to show in a drop-down list the content of the queryresult. This result, has a string field with strings that sometimes has the single quote symbol or the written accent: ( ' or ´ ) and when these strings are shown has the symbol "?" instead of the correct one.
and when these strings are shown has the symbol "?" instead of the correct one
What code are you using to display the result of the query? Are you saying that the FeatureSets feature attributes actually have the "?" in the returned data or is it something about your code for diaplying the results that is adding the "?" ?
