diff trunk/src/dil/Scope.d @ 430:e6c759e151cd

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fixed a few things regarding encoding/decoding UTF-8 sequences. When an escape sequence was scanned with an invalid Unicode code point then an error is reported and REPLACEMENT_CHAR is encoded instead. The same is done when an invalid UTF-8 sequence was encountered. Added a few stub methods to class Scope.
