[libredwg] unicode

[Till Heuschmann]

Hi,

Has someone ever thought about how we could handle unicode texts?

Starting with R2007 the text in the .dwg files are stored in utf16 and 
therefore the actual char strings are somewhat too small.

To deal with this we could:

1) Use wchar_t as the character type for all strings and convert the strings in 
older files when they are read.
2) Manage two different versions of a string and perform the conversion when 
the string is accessed.
3) ???

Any thoughts/experiences on this?
