There is an annoying error in MultiByteFileStream, reading back when you have a unicode character. It is also the cause of some FileOut errors. Your can reproduce it this way:
testString := 'abcdé'. filename := 'test.txt'. filename asFileReference ensureDelete. filename asFileReference writeStreamDo: [ :stream | stream nextPutAll: testString ]. f := 'test.txt' asFileReference readStream. f setToEnd. f skip: -1. f peek. Any ideas how to solve it? Avoiding reading back is not an option ;). Maybe making skip to go back one more byte to check if there is a unicode character around?. Thanks a lot.
