The default ODBC driver manager on MacOSX is iODBC, which uses "typedef wchar_t SQLWCHAR" on POSIX platforms. This clashes with Tcl's "typedef unsigned short Tcl_UniChar". I've tried to solve this in AndroWish/undroidwish with check-in https://www.androwish.org/index.html/ci/868b1367382d582f and tested it with the SQLite3 ODBC driver on MacOSX. The strange observation was that the iODBC translation layer, which converts between wide-char and ANSI entry points, is buggy regarding character counting. The temporary solution was to build the SQLite3 ODBC driver explicitely with wide-char interfaces (configure option --with-winterface). chw added on 2018-01-07 10:46:58: Meanwhile I've updated the iODBC support for MacOSX (and OpenBSD) for version 1.0.6 in this check-in: https://www.androwish.org/index.html/info/d51247f537442255 kbk added on 2018-06-19 01:21:47: Fixed in 1.1.0 | ||||
