Access and shortcut keys: Short cut keys doesnot contains characters from the double bite character. Bitmaps and Icons: These functionality dont use in text when working with bit maps and icons consider of following rules. Bit maps which are not international standards avoid using them.

UI controls: There are so many UI controls like buttons, List boxes, Combo boxes etc.,These are the building blocks of dailogue boxes. - Hiding a control behind another control is not the correct way to locate it. It will happen due to language expansion. - By using controls as part os scentences the sentences suffer the same problem as concatenation strings. Messages: Text strings are usually larger than english text strings in other languages. The growth rate which is acute in short strings become less of a problem as string length increases. .
