- Added configuration for test paths in CMake to simplify file references.
- Updated load_test.cpp and various unit tests to use defined path macros for dictionary and test data files.
- Introduced test_paths.h.in to manage directory paths consistently across tests.
Updated multiple files to replace instances of DecodeRunesInString with DecodeUTF8RunesInString, ensuring proper handling of UTF-8 encoded strings. This change enhances the robustness of string decoding across the cppjieba library, including updates in DictTrie, HMMModel, PosTagger, PreFilter, SegmentBase, and Unicode files. Additionally, corresponding unit tests have been modified to reflect these changes.
