Hello.
printf("<p class = \"CBL\"><a name = \"CBL\">%lc</a></p>", wcCityName[0]);
In this code string format specifier lc marked as wrong because wcCityName[0] variable is treated as integer while it is wide char.

Best regards, Daniil.
Comment 1 Vladimir Voskresensky 2016-05-05 22:26:42 UTC 
Could you, please, provide declaration of wcCityName.

Thanks!
Comment 2 noisebringer 2016-05-06 02:24:39 UTC 
wchar_t *wcCityName = NULL;
Comment 3 noisebringer 2016-05-06 02:31:37 UTC 
Then some memory is allocated for it with 
wcCityName = realloc(wcCityName, strlen(Row[1]) * WCHAR_SIZE);

and it is filled with
mbstowcs(wcCityName, Row[1], strlen(Row[1]));

Where Row[1] is char pointer which is fetched from mysql result.
Comment 4 danilasergeyev 2016-07-20 10:13:46 UTC 
The issue is that wchar_t* is recognized as just wchar_t
Comment 5 danilasergeyev 2016-07-20 13:39:37 UTC 
Sorry, I was wrong. Everything recognized correctly and we shouldn't mark %lc for wchar_t as error.
