For a UTF-8 string, the size needed for UTF-32 is no more than four 1744 times, because up to 0xffff uses no more than 3 bytes in UTF-8 but possibly 4 1745 in UTF-32. Higher values use 4 bytes in UTF-8 and up to 4 bytes in UTF-32. The 1746 result is always left in buffer32. 1747 1748 Note that this function does not object to surrogate values. This is 1749 deliberate; it makes it possible to construct UTF-32 strings that are invalid, 1750 for the purpose of testing that they are correctly faulted. 1751 1752 Patterns to be converted are either plain ASCII or UTF-8; data lines are always 1753 in UTF-8 so that values greater than 255 can be handled. 1754 1755 Arguments: 1756 data TRUE if converting a data line; FALSE for a regex 1757 p points to a byte string 1758 utf true if UTF-8 (to be converted to UTF-32) 1759 len number of bytes in the string (excluding trailing zero) 1760 1761 Returns: number of 32-bit data items used (excluding trailing zero) 1762 OR -1 if a UTF-8 string is malformed 1763 OR -2 if a value > 0x10ffff is encountered 1764 OR -3 if an ill-formed value is encountered (i.e. a surrogate) 1765 */ 1766 1767 static int 1768 to32(int data, pcre_uint8 *p, int utf, int len) 1769 { 1770 pcre_uint32 *pp; 1771 1772 if (buffer32_size < 4*len + 4) 1773 { 1774 if (buffer32 != NULL) free(buffer32); 1775 buffer32_size = 4*len + 4; 1776 buffer32 = (pcre_uint32 *)malloc(buffer32_size); 1777 if (buffer32 == NULL) 1778 { 1779 fprintf(stderr, "pcretest: malloc(%d) failed for buffer32\n", buffer32_size); 1780 exit(1); 1781 } 1782 } 1783 1784 pp = buffer32; 1785 1786 if (!utf && !data) 1787 { 1788 while (len-- > 0) *pp++ = *p++; 1789 } 1790 1791 else 1792 { 1793 pcre_uint32 c = 0; 1794 while (len > 0) 1795 { 1796 int chlen = utf82ord(p, &c); 1797 if (chlen <= 0) return -1; 1798 if (utf) 1799 { 1800 if (c > 0x10ffff) return -2; 1801 if (!data && (c & 0xfffff800u) == 0xd800u) return -3; 1802 } 1803 1804 p += chlen; 1805 len -= chlen; 1806 *pp++ = c; 1807 } 1808 } 1809 1810 *pp = 0; 1811 return pp - buffer32; 1812 } 1813 1814 /* Check that a 32-bit character string is valid UTF-32. 1815 1816 Arguments: 1817 string points to the string 1818 length length of string, or -1 if the string is zero-terminated 1819 1820 Returns: TRUE if the string is a valid UTF-32 string 1821 FALSE otherwise 1822 */ 1823 1824 #ifdef NEVER /* Not used */ 1825 #ifdef SUPPORT_UTF 1826 static BOOL 1827 valid_utf32(pcre_uint32 *string, int length) 1828 { 1829 register pcre_uint32 *p; 1830 register pcre_uint32 c; 1831 1832 for (p = string; length-- > 0; p++) 1833 { 1834 c = *p; 1835 if (c > 0x10ffffu) return FALSE; /* Too big */ 1836 if ((c & 0xfffff800u) == 0xd800u) return FALSE; /* Surrogate */ 1837 } 1838 1839 return TRUE; 1840 } 1841 #endif /* SUPPORT_UTF */ 1842 #endif /* NEVER */ 1843 #endif /* SUPPORT_PCRE32 */ 1844 1845 1846 /************************************************* 1847 * Read or extend an input line * 1848 *************************************************/ 1849 1850 /* Input lines are read into buffer, but both patterns and data lines can be 1851 continued over multiple input lines.
