pcre32: pcretest: Don't convert data line to UTF-8 first

While reading the data lines, directly put them into the 8, 16 or
32 bit buffers instead of first converting them into UTF-8 and only
afterwards converting that buffer to 16/32 bit. This is necessary so
the in 32 bit mode the \x{} escapes can use the full 32-bit range
(while the non-standard 5/6 byte UTF-8 sequences can only express
characters up to 31-bits).

114 /* When compiling a DLL for Windows, the exported symbols have to be declared
115 using some MS magic. I found some useful information on this web page:
116 http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
117 information there, using __declspec(dllexport) without "extern" we have a
118 definition; with "extern" we have a declaration. The settings here override the
119 setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
120 which is all that is needed for applications (they just import the symbols). We
121 use:
122
123 PCRE_EXP_DECL for declarations
124 PCRE_EXP_DEFN for definitions of exported functions
125 PCRE_EXP_DATA_DEFN for definitions of exported variables
126
127 The reason for the two DEFN macros is that in non-Windows environments, one
128 does not want to have "extern" before variable definitions because it leads to
129 compiler warnings. So we distinguish between functions and variables. In
130 Windows, the two should always be the same.
131
132 The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
133 which is an application, but needs to import this file in order to "peek" at
134 internals, can #include pcre.h first to get an application's-eye view.
135
136 In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
137 special-purpose environments) might want to stick other stuff in front of
138 exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
139 PCRE_EXP_DATA_DEFN only if they are not already set. */

1124 which is different from their ASCII/UTF-8 code. Instead we define macros for
1125 the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
1126 is enabled. When UTF-8 support is not enabled, the definitions use character
1127 literals. Both character and string versions of each character are needed, and
1128 there are some longer strings as well.
1129
1130 This means that, on EBCDIC platforms, the PCRE library can handle either
1131 EBCDIC, or UTF-8, but not both. To support both in the same compiled library
1132 would need different lookups depending on whether PCRE_UTF8 was set or not.
1133 This would make it impossible to use characters in switch/case statements,
1134 which would reduce performance. For a theoretical use (which nobody has asked
1135 for) in a minority area (EBCDIC platforms), this is not sensible. Any
1136 application that did need both could compile two versions of the library, using

1771 definitions below, up to ESC_z. There's a dummy for OP_ALLANY because it
1772 corresponds to "." in DOTALL mode rather than an escape sequence. It is also
1773 used for [^] in JavaScript compatibility mode, and for \C in non-utf mode. In

1776 The special values ESC_DU, ESC_du, etc. are used instead of ESC_D, ESC_d, etc.
1777 when PCRE_UCP is set and replacement of \d etc by \p sequences is required.

1781 Negative numbers are used to encode a backreference (\1, \2, \3, etc.) in

1783 greater than ESC_b and less than ESC_Z to detect the types that may be
1784 repeated. These are the types that consume characters. If any new escapes are
1785 put in between that don't consume a character, that code will have to change.
