Correctly reset streamsafe iterator #62

Closed Manishearth closed 3 years ago

The attached test was failing otherwise, (credit @sunfishcode). We basically did not take into account the decomposition width of the next character when buffering after a combining grapheme joiner.

We should probably add fuzz targets for this stuff using cargo-fuzz.

Merging since this could be a security issue, feel free to review ex post facto.
