** Big Maps Projects code (incl. Multiplayer v1.5 **
**********************************************************
- Merged Big Maps Project code from BMP+MP trunk (Revision: 3340)
o Complete SVN Revision history: https://81.169.133.124/source/ja2/branches/Wanne/JA2%201.13%20MP
- Before THIS merge, I made a branch of the existing 1.13 source
o SVN Branch: https://81.169.133.124/source/ja2/branches/JA2_rev.3336/src
- Removed old VS 6.0 and VS 2003 project and solutions files, because compilation is broken long time ago
- I will add VS 2010 projects and solution file in the next few days

git-svn-id: https://ja2svn.mooo.com/source/ja2/trunk/GameSource/ja2_v1.13/Build@3341 3b4a5df2-a311-0410-b5c6-a8a6f20db521

Many C++ developers miss an easy and portable way of handling Unicode encoded
strings. C++ Standard is currently Unicode agnostic, and while some work is being
done to introduce Unicode to the next incarnation called C++0x, for the moment
nothing of the sort is available. In the meantime, developers use 3rd party
libraries like ICU, OS specific capabilities, or simply roll out their own
solutions.

To illustrate the use of this utf8 library, we shall open a file containing UTF-8
encoded text, check whether it starts with a byte order mark, read each line into a
<code>std::string</code>, check it for validity, convert the text to UTF-16, and
back to UTF-8:
To illustrate the use of the library, let's start with a small but complete program
that opens a file containing UTF-8 encoded text, reads it line by line, checks each line
for invalid UTF-8 byte sequences, and converts it to UTF-16 encoding and back to UTF-8:

In the previous code sample, we have seen the use of the following functions from
<code>utf8</code> namespace: first we used <code>is_bom</code> function to detect
UTF-8 byte order mark at the beginning of the file; then for each line we performed
In the previous code sample, for each line we performed
a detection of invalid UTF-8 sequences with <code>find_invalid</code>; the number
of characters (more precisely - the number of Unicode code points) in each line was
of characters (more precisely - the number of Unicode code points, including the end
of line and even BOM if there is one) in each line was
determined with a use of <code>utf8::distance</code>; finally, we have converted
each line to UTF-16 encoding with <code>utf8to16</code> and back to UTF-8 with
<code>utf16to8</code>.
</p>
<h3 id="validfile">Checking if a file contains valid UTF-8 text</h3>
<p>
Here is a function that checks whether the content of a file is valid UTF-8 encoded text without
reading the content into the memory:
</p>
<pre>
<span class="keyword">bool</span> valid_utf8_file(i<span class="keyword">const char</span>* file_name)
{
ifstream ifs(file_name);
<span class="keyword">if</span> (!ifs)
<span class="keyword">return false</span>; <span class="comment">// even better, throw here</span>
istreambuf_iterator&lt;<span class="keyword">char</span>&gt; it(ifs.rdbuf());
istreambuf_iterator&lt;<span class="keyword">char</span>&gt; eos;
<span class="keyword">return</span> utf8::is_valid(it, eos);
}
</pre>
<p>
Because the function <code>utf8::is_valid()</code> works with input iterators, we were able
to pass an <code>istreambuf_iterator</code> to it and read the content of the file directly
without loading it to the memory first.</p>
<p>
Note that other functions that take input iterator arguments can be used in a similar way. For
instance, to read the content of a UTF-8 encoded text file and convert the text to UTF-16, just
do something like:
</p>
<pre>
utf8::utf8to16(it, eos, back_inserter(u16string));
</pre>
<h3 id="fixinvalid">Ensure that a string contains valid UTF-8 text</h3>
<p>
If we have some text that "probably" contains UTF-8 encoded text and we want to
replace any invalid UTF-8 sequence with a replacement character, something like
the following function may be used:
</p>
<pre>
<span class="keyword">void</span> fix_utf8_string(std::string&amp; str)
{
std::string temp;
utf8::replace_invalid(str.begin(), str.end(), back_inserter(temp));
str = temp;
}
</pre>
<p>The function will replace any invalid UTF-8 sequence with a Unicode replacement character.
There is an overloaded function that enables the caller to supply their own replacement character.
