DESCRIPTION

Convert UTF8-character to lowercase.

EXAMPLE

int codept;
char cbuf[8];
int no_bytes;

/* set UTF8-character into cbuf */
strcpy(cbuf, "Ö");

/* get unicode-codepoint */
no_bytes = vg4->misc->utf8_next(cbuf, strlen(cbuf), &codept);
if (no_bytes <= 0) { exit(1); }
printf("UTF8-character(%d)=%s\n", codept, cbuf);

/* convert to lowercase */
codept = vg4->misc->utf8_tolower(codept);
no_bytes = vg4->misc->utf8_from_codepoint(codept, cbuf);
cbuf[no_bytes] = '\0';
printf("Lowercase UTF8-character(%d)=%s\n", codept, cbuf);

Output:
UTF8-character(214)=Ö
Lowercase UTF8-character(246)=ö
