Open the example modelrtwdemo_unicode.

Labels in the model appear in multiple languages (Arabic, Chinese, English, German, and Japanese) and various Unicode symbols.

model ='rtwdemo_unicode';open_system(model);

Verify Locale Settings

Verify that the locale setting for your MATLAB® software is compatible with your compiler. See the documentation for your operating system or the following MATLAB documentation:

Verify Model for Use of Foreign Characters

to verify the model for characters that the code generator cannot represent in the model's current character set encoding, use the Simulink® Model Advisor checkCheck model for foreign characters.

1.Open the Model Advisor in Simulink®. SelectAnalysis>Model Advisor>Model Advisor. Or, in the Command Window, type:

modeladvisor('rtwdemo_unicode')

Loading Model Advisor cache… Warning: Cannot load an object of class 'SDRSLHDLWAPlugin': Its class cannot be found. Warning: Cannot load an object of class 'SDRSLHDLWAPlugin': Its class cannot be found. Model Advisor cache loaded. For new customizations, to update the cache, use the Advisor.Manager.refresh_customizations method. Updating Model Advisor cache… Model Advisor cache updated. For new customizations, to update the cache, use the Advisor.Manager.refresh_customizations method.

2.ExpandBy Product.

3.Expand金宝app.

4.SelectCheck model for foreign characters

5.ClickRun This Check.

6.Review the results. Several warnings appear. Verify that the characters in the model can be represented in the current character set encoding.

7.Close the Model Advisor.

Code Generation Template Files

To use a code generation template file with unicode characters when generating code, complete these steps (requires Embedded Coder®). Otherwise, go to the next section.

1.Open the Configuration Parameters dialog box.

2.Navigate to theCode Generation > Templatepane. The model is configured to use the code generation template filertwdemo_unicode.cgt. That file adds comments to the top of generated code files. For the code generator to apply escape sequence replacements for the.cgtfile, enable replacements by specifying:

3.Open the file/工具箱/ rtw / rtwdemos / rtwdemo_unicode.cgt.

edit rtwdemo_unicode.cgt

4.Find the line of code that enables escape sequence replacements for the character set encodingUTF-8.

5.Close the file/工具箱/ rtw / rtwdemos / rtwdemo_unicode.cgt.

Generated File Customization Template

使用unicode c文件定制模板haracters when generating code, complete these steps (requires Embedded Coder®). Otherwise, go to the next section.

You can specify customizations to generated code files by using TLC code. TLC files support user default encoding only. To produce international custom generated code that is portable, use the 7-bit ASCII character set.

1.Open the Configuration Parameters dialog box.

2.Navigate to theCode Generation > Templatepane. The model is configured to use the code customization fileexample_file_process.tlc. That file customizes the generated code just before the code generator writes the code files. For example, the file adds a C source file, corresponding include file, and#defineand#includestatements.

3.Open the file/toolbox/rtw/rtwdemos/example_file_process.tlc.

edit example_file_process.tlc

4.Before generating code, uncomment the following line of code:

% % %分配ERTCustomFileTest = TLC_TRUE%

5.Close the file/工具箱/ rtw / rtwdemos / rtwdemo_unicode.cgt.

Generate C Code

Generate C code and a code generation report.

evalc('rtwbuild(''rtwdemo_unicode'')');

Review the Generated Code

For characters that are not in the current MATLAB® character set encoding, the code generator uses escape sequence replacements to render characters correctly in the code generation report.

1.If the code generation report for modelrtwdemo_unicodeis not open, in the Command Window, type:

coder.report.open('rtwdemo_unicode')

2.Review the generated code inrtwdemo_unicode.candrtwdemo_unicode.h. Names of model elements appear in code comments as replacement names in the local language.

3.Open the Traceability Report. The report maintains traceability information, even when the name contains characters that are not represented in the current encoding. Names of model elements appear in the report as replacement names in the local language.

4.Scroll down to and click the code location link for the first Chart (State 'Selection' :23). The report view changes to show the corresponding code inrtwdemo_unicode.c.

5.In the code comment, click the:23link. The model window shows the chart in a new tab.

6.In the model window, right-click that chart. SelectC/C++ Code > Navigate to C/C++ Code. The report view changes to show the named constant section of code for that chart.

7.Close the code generation report, Model Advisor, and model. In the Command Window, type:

coder.report.close(); bdclose('all');

Generate C++ Code

Generate C++ code and a code generation report.

1.Open the model.

model ='rtwdemo_unicode';open_system(model);

2.ChangeConfiguration Parameters>Code Generation>LanguagetoC++. Or, in the Command Window, type:

set_param('rtwdemo_unicode','TargetLang','C++');

3.ChangeConfiguration Parameters>Code Generation>Interface>Code interface packagingtoC++ class. Or, in the Command Window, type:

set_param('rtwdemo_unicode','CodeInterfacePackaging','C++ class');

4.Generate C++ code and a code generation report.

evalc('rtwrebuild(''rtwdemo_unicode'')');

5.To see internationalization and localization support, review the generated code. SeeReview the Generated Code.

6.Close the code generation report and model. In the Command Window, type:

coder.report.close(); bdclose('all');
