Yes. When you unicode2native a character that has no counterpart in the destination character set, then binary 26 is substituted.

S = char(['How now?', 2000:2029, ' brown cow'])
S = 'How now?ߐߑߒߓߔߕߖߗߘߙߚߛߜߝߞߟߠߡߢߣߤߥߦߧߨߩߪ߫߬߭ brown cow'
B = unicode2native(S, 'windows-1252')
B = 1×48
    72   111   119    32   110   111   119    63    26    26    26    26    26    26    26    26    26    26    26    26    26    26    26    26    26    26    26    26    26    26
B(B == 26) = []
B = 1×18
    72   111   119    32   110   111   119    63    32    98   114   111   119   110    32    99   111   119
Sback = native2unicode(B, 'windows-1252')
Sback = 'How now? brown cow'
