Create a string from the C string array. This is most commonly used with a literal string, eg "hello". A new memory block is allocated of a size sufficient to take the length of the string and its terminating '\0' character.
<p>
If UCS-2 is used then each char from the char pointer is mapped to a single UCS-2 character. <dl compact><dt><b>Parameters: </b></dt><dd>

Create a string from the array. A new memory block is allocated of a size equal to len# plus one which is sufficient to take the string and a terminating '\0' character.

If UCS-2 is used then each char from the char pointer is mapped to a single UCS-2 character.
<p>
Note that this function will allow a string with embedded '\0' characters to be created, but most of the functions here will be unable to access characters beyond the first '\0'. Furthermore, if the <a class="el" href="classPString.html#z237_0">MakeMinimumSize()</a># function is called, all data beyond that first #'\0'# character will be lost. <dl compact><dt><b>Parameters: </b></dt><dd>
