The changes include: 1. Updating the `utf8_to_wide` and `wide_to_utf8` functions to handle UTF-32 on Unix/Linux platforms. 2. Updating the `copy_from_string` function to handle UTF-16 on Windows and convert UTF-32 to UTF-16 on other platforms. 3. Updating the `bind_by_pos` function to handle UTF-16 on Windows and convert UTF-32 to UTF-16 on other platforms. 4. Adding a test case for wide strings in the ODBC MSSQL tests. --- include/private/soci-unicode.h | 369 ++++++++++++++--------- include/soci/odbc/soci-odbc.h | 2 - include/soci/soci-unicode.h | 184 ----------- src/backends/odbc/standard-into-type.cpp | 12 +- src/backends/odbc/standard-use-type.cpp | 15 + tests/odbc/test-odbc-mssql.cpp | 4 +- 6 files changed, 249 insertions(+), 337 deletions(-) delete mode 100644 include/soci/soci-unicode.h diff --git a/include/private/soci-unicode.h b/include/private/soci-unicode.h index 54b7be641..aae43f5f9 100644 --- a/include/private/soci-unicode.h +++ b/include/private/soci-unicode.h @@ -1,184 +1,267 @@ #ifndef SOCI_PRIVATE_SOCI_UNICODE_H_INCLUDED #define SOCI_PRIVATE_SOCI_UNICODE_H_INCLUDED -#include #include +#include #include "soci/error.h" namespace soci { -namespace details -{ - - // Interface functions -#if defined(_MSC_VER) || defined(__MINGW32__) - + namespace details + { - inline std::wstring utf8_to_utf16(const std::string& utf8) { - std::wstring utf16;
