The engine absorbed the six local mode queries during the cross-platform work,
and MSIME-Linux has been driving them in production since. This repository kept
its own implementations of the same six features, so date-time, emoji, kaomoji,
jianpin, quick-phrase and unicode each existed twice and were free to drift.
Deletes this repository's copies and points the eight call sites in
event_listener.cpp plus the two async workers at metasequoia::local_modes.
The shuangpin profile is the part to look at. The old modules resolved the
*configured* scheme themselves:
GetShuangpinProfile(shuangpin_schema.empty() ? GetConfiguredShuangpinSchema()
: shuangpin_schema)
The engine takes a resolved ShuangpinProfile and defaults it to Xiaohe. Taking
that default would have decoded J mode, emoji and kaomoji as Xiaohe for every
user on Ziranma, Shoudao or Microsoft shuangpin, so every call site passes the
configured profile explicitly through a ConfiguredShuangpinProfile() helper.
The database path needs the same care in the other direction. The old modules
took a UTF-8 std::string and handed it straight to sqlite3_open_v2; the engine
takes a std::filesystem::path and converts back with path_to_utf8 before
opening. The two async workers therefore bridge with path_from_utf8 rather than
constructing a path from the narrow string, which on Windows would interpret a
non-ASCII data directory in the active code page.
The four existing test files are kept and re-pointed at the engine functions
with every expectation byte-identical, including the seventeen date-time format
strings and the four shuangpin schemes jianpin covers. They are the equivalence
check: if the engine's port diverged from what this repository shipped, those
assertions fail rather than the difference reaching users.
