Why does Real-Time Workshop crash when code generation is performed on block diagrams with multibyte characters?

Using multibyte characters (e.g., Japanese extended character set) in Simulink causes Real-Time Workshop to crash during code generation, or yields unexpected results.

This bug has been fixed for Release 14 (R14). For previous releases, please read below for any possible workarounds:

This has been verified as a bug in Real-Time Workshop 5.1 (R13SP1) in the way that the TLC compiler handles multibyte characters.

Currently, you can download a revised version of a library file that fixes the problem. Here are the required steps:

1. Quit MATLAB

2. Rename the following file:

PC: $MATLAB/toolbox/rtw/rtw/tlc_new.dll

Linux: $MATLAB/toolbox/rtw/rtw/tlc_new.mexglx

(where $MATLAB = the MATLAB root directory on your machine)

Rename the file to [filename].old

3. Download one of the following files found as an attachment at the end of this article:

PC: tlc_new.dll

Linux: tlc_new.mexglx

and place it in the same directory mentioned in step 2.

4. Restart MATLAB

5. After restarting MATLAB, issue the following command at the MATLAB prompt:
