    libstdc++: Add missing character to __to_wstring_numeric map
    
    The mapping from char to wchar_t needs to handle 'i' and 'I' but those
    were absent from the table that is used for some non-ASCII encodings.
    
    libstdc++-v3/ChangeLog:
    
            * include/bits/basic_string.h (__to_wstring_numeric): Add 'i'
            and 'I' to mapping.
    
    (cherry picked from commit e1937cf33abded5c6ebbe4938a4a3e8cb3365176)
