How to display Chinese character in gui table / command window
Show older comments
Hello, I want to display Chinese character in gui table or command window, how to do that? Such as I want "单位" displayed in command window, I use
str = '单位'
then I got this
str =
位
When I read EXCEL by GUI table, it is same. What can I do? And I do not want to change any property or setting with my environment. So is there some code I can use like
str = ['<html> strtype="UTF-8", str='单位'<html>'] %dummy code
PS: I use a Japanese Windows system, and Chinese character could correctly displayed in text/folder name/excel and so on.
Sorry for my English.
Thanks.

Hello kei hin,
there is one possibility to display chinese characters by switching the default character set to UTF-8 as described here: https://de.mathworks.com/matlabcentral/answers/116527-how-to-display-chinese-character-in-edit-text-box-in-matlab-gui
or try the following function, that worked on my machine (commented lines are for try in case the code does not work on your machine properly):
function drawTable(Data)
% %%Change default character set
% defCharSet = feature('DefaultCharacterSet', 'UTF8');
% %%Add html tag to Data
% Data(:) = strcat('<html><meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />', ...
% Data(:));
%%Plot figure and uitable
f = figure;
t = uitable(f,'ColumnFormat',[],'Data',Data,'ColumnWidth',{50});
% %%Restore default char set
% feature('DefaultCharacterSet', defCharSet);
end
Kind regards,
Robert

Calling
feature('DefaultCharacterSet')
shows your default character set.
The feature()-function is undocumented. You can find a similar question with answer by Walter Roberson using the "Search Answers"-Feature on this website (see web-link in my answer).
Kind regards,
Robert
PS: The standard character set on my machine is 'windows-1252'. Yours might be different.

Hello kei hin,
the function call
%%Change default character set
defCharSet = feature('DefaultCharacterSet', 'UTF8');
sets your actual character set to UTF-8 and returns the previously set character set, saving it in the variable "defCharSet".
The function head can be read from Matlab path "YourMatlabRootFolder"\toolbox\distcomp\@distcomp\feature.m as
function oldValue = feature( name, optValue )
;%#ok<NOSEM> undocumented
in version R2014b.
Thus, restoring the previously set character set can be done by calling
feature('DefaultCharacterSet', defCharSet);
No return variable is needed, since you know the character set you are changing back from.
Kind regards,
Robert

Are you using the above solution as script-code or as function (as presented above)?
First, as script it did not work at any time. Calling the function surprisingly did work.
Check whether your variable is stored correctly:
% write 单 into a variable
TestVar = char('单');
dec2hex(double(TestVar))
Check in workspace whether TestVar contains the correct character or a replacement character. If there is a replacement character try the next 'DefaultCharacterSet'.
% compare hexadecimal representation of '单' in actual encoding
dec2hex(double('单'))
char(hex2dec('5355'))
Kind regards,
Robert

A variable assigned inside the function is not stored correctly but by the replacement character '3F'. Strangely, throwing the function input directly to uitable does not cause any problem.
