toHTML - convert Unicode string(s) to HTML

TOHTML Converts strings to their UTF-8 HTML representation
str = TOHTML(str) converts the input string or cell array of strings to its Unicode representation in HTML. All characters but one: any occurrence of the newline character (char(10)) will be converted to the string '<br>'.
This function is most useful when creating buttons in a GUI, that need to contain a multi-line string with Unicode characters. For example:

EXAMPLE:

uicontrol(...
'style' , 'pushbutton',...
'units' , 'normalized',...
'string' , toHTML(['θ·Ω' char(10) 'A×B']),...
'position', [0.05 0.05 0.1 0.1]...
);
