    <p>I am trying to open a .txt file that is wholly Chinese. Can I use normal fopen/fclose procedures to it even though the stream would be 100% Unicode or are there any exlusive tools for handling wide characters? I'd be grateful for precise answers, I am a beginner programmer. I am using Linux with standard gcc.</p> <p>I will attach my code, it compiles with no error but upon execution I get segmentation fault. I don't know what is wrong with it. The point of this programme is to copy each string of Chinese signs in which a specific sign from a given set is to be found and to write it in a separate file.</p> <pre><code>#include&lt;stdio.h&gt; #include&lt;stdlib.h&gt; #include&lt;wchar.h&gt; #include &lt;locale.h&gt; #define PLIK_IN in /*filenames*/ #define PLIK_OUT out #define LKON 49 /*specifying the length of a string on the left from a desired sign*/ #define PKON 50 /*...and on the right*/ int wczytaj_pliki(FILE*, FILE*); /*open file*/ void krocz_po_pliku(FILE*, FILE*); /*search through file*/ int slownik(wchar_t); /*compare signs*/ void zapisz_pliki(FILE*, FILE*); /*write to file*/ void main(void) { FILE *bin,*bout; setlocale(LC_CTYPE, ""); wczytaj_pliki(bin, bout); krocz_po_pliku(bin, bout); zapisz_pliki(bin, bout); }/*main*/ int slownik(wchar_t znak) /*compare characters*/ { wchar_t gznak1 = L'股', gznak2 = L'利', gznak3 = L'红'; if ( ( znak == gznak1) || (znak == gznak2) || (znak == gznak3) ) return 1; return 0; }/*slownik*/ void krocz_po_pliku(FILE* bin, FILE* bout) /*search through file*/ { wchar_t wch; wchar_t* kontekst; int i = 0, j, step = LKON, counter = 0, token = 0; while ( (wch = getwchar() ) != EOF ) { if (!token) /*comparing consecutive signs*/ { if ( slownik(wch) == 1 ) { counter++; fprintf(bout,"###Wystapienie %d.\n\n", counter); if ( i&lt;step ) step = i; fseek(bin,-step,1); j=0, token = 1; }/*if*/ else i++; }/*if*/ else /*writing consecutive signs within context*/ { if ( j &lt; LKON + PKON) { putwc(wch, bout); j++; }/*if*/ else { fprintf(bout,"###\n\n"); fflush(bout); token = 0; }/*else*/ }/*else*/ }/*while*/ printf("Znalazlem %d wystapien\n", counter); }/*krocz_po_pliku*/ int wczytaj_pliki(FILE* bin, FILE* bout) { bin=fopen("PLIK_IN","r"); bout=fopen("PLIK_OUT","w"); rewind(bin); if(bin==NULL || bout==NULL) { printf("Blad plikow\n"); exit(0); }/*if*/ return 1; }/*wczytaj pliki*/ void zapisz_pliki(FILE* bin, FILE* bout) { fclose(bin); fclose(bout); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
