I found solution.
I comment line of code in scanning loop in
MultiCharacterScanner>>scanMultiCharactersFrom: startIndex to: stopIndex in:
sourceString rightX: rightX stopConditions: stops kern: kernDelta
...
"encoding ~= startEncoding ifTrue: [lastIndex := lastIndex - 1. ^
stops endOfRun]."
...
Without this commenting scanning process not register breakage at space when
scanning russian text. (because encoding is differ from startEncoding.
Encoding for space is 0 but for startEncoding is leadingChar of not ascii
russian text).
I dont now meaning of this code line. But now I have correct wrapping
behavior.
I know that multilingual package have many newly versions. All containes
that strange code line.
I open Issue http://code.google.com/p/pharo/issues/detail?id=2608
