Hello
It looks like there's a problem on WinCE operating system with the
utf8ToUnicode() / unicodeToUtf8() conversion functions. No database
can be opened by sqlite3_open() because thehes functions fail.
Please have a look what happens there (location: os_win.c :)
/*
** Convert a UTF-8 string to microsoft unicode (UTF-16?).
**
** Space to hold the returned string is obtained from
sqliteMalloc.
*/
static WCHAR *utf8ToUnicode(const char *zFilename){ // ->->->
zFilename is "mydatabase.db"
int nChar;
WCHAR *zWideFilename;
nChar = MultiByteToWideChar(CP_UTF8, 0, zFilename, -1, NULL, 0);
// ->->-> returns 0 here
zWideFilename = sqliteMalloc( nChar*sizeof(zWideFilename[0]) );
// ->->-> returns null pointer
if( zWideFilename==0 ){
return 0;
// ->->-> leaves function here
}
nChar = MultiByteToWideChar(CP_UTF8, 0, zFilename, -1,
zWideFilename, nChar);
if( nChar==0 ){
sqliteFree(zWideFilename);
zWideFilename = 0;
}
return zWideFilename;
}
If I use the CP_ACP flag, everthing works ok:
nChar = MultiByteToWideChar(CP_ACP, 0, zFilename, -1, NULL, 0);
Same failure probably in unicodeToUtf8() because it uses
"WideCharToMultiByte(CP_UTF8, 0, zWideFilename, -1, 0, 0, 0, 0);"
My question:
Is this a bug or is something wrong with my WinCE-Image?
Version information
SQLite 3.3.17 (also tried 3.3.13 and failed)
WinCE 5.0

Daniel
