I am running Real-Time Workshop and I am trying to include multibyte Japanese characters in my .tlc file. But when I use the TLC command:

tlc -v mytest.tlc

I receive the following crash report:

Also, TLC gives a wrong result on multi-byte characters. The multibyte strings are being truncated.

I was able to use TLC without problem with Real-Time Workshop 5.0 (R13).

This bug has been fixed for Release 14 (R14). A bug in Release 13 Service Pack 1 caused wrong answers and possibly crashes to occur when multi-byte characters (Unicode) were included in TLC scripts. This has been fixed, restoring the correct handling found in R13. Also, insufficient memory allocation was causing the truncation of multi-byte strings. This behavior has been fixed.
