[PATCH] unicode: replace strncpy() by strscpy()

[Gustavo A. R. Silva]

The strncpy() function is being deprecated. Replace it by the safer
strscpy() and fix the following Coverity warning:

"Calling strncpy with a maximum size argument of 12 bytes on destination
array version_string of size 12 bytes might leave the destination string
unterminated."

Notice that, unlike strncpy(), strscpy() always null-terminates the
destination string.
