Add Character-Spacing value attribute "char-space-value" to span tag.
How to apply it in TextEditor:
textEditor.SetProperty(Dali::Toolkit::TextEditor::Property::TEXT,
"<span font-size='20' font-family='DejaVu Sans' font-width='condensed' font-slant='italic' text-color='blue' >ABC EF\n</span>"
"<span font-size='20' font-family='DejaVu Sans' font-width='condensed' font-slant='italic' text-color='red' char-space-value='-5.0f'>ABC EF\n</span>"
"<span font-size='20' font-family='DejaVu Sans' font-width='condensed' font-slant='italic' text-color='green' char-space-value='10.0f'>ABC EF\n</span>");
textEditor.SetProperty(Dali::Toolkit::TextEditor::Property::ENABLE_MARKUP, true);
