Problem on Windows:
==================
LLPanelMainInventory::updateItemcountText() formats number using viewer locale.
non-break space is detected as unknown symbols while converting utf8str_to_wstring when formatted text is set to LLTextBox.
FIX:
===
Added converting of string to multi-byte string and then to utf8 string while formatting on Windows.
created opposite to "ll_convert_wide_to_string" function "ll_convert_string_to_wide" and helper function to call both of them.
It is used now to convert result of formatted string while formatting integer number in locale.
Fix affects Windows only.
