    private Context mContext;

    public CalligraphyTextInputLayout(Context context) {
        this(context, null, 0);
    }

    public CalligraphyTextInputLayout(Context context, AttributeSet attrs) {
        this(context, attrs, 0);

        super(context, attrs, defStyleAttr);
        mContext = context;
    }

    @Override
    public void setError(@Nullable CharSequence error) {
        Spannable spannable = null;
        if (!TextUtils.isEmpty(error))
            spannable = wrapInCustomFont(mContext, error.toString());

        super.setError(spannable);
    }

    private Spannable wrapInCustomFont(Context context, String text) {
        CalligraphyTypefaceSpan typefaceSpan = new CalligraphyTypefaceSpan(getTypeFace(context));
        SpannableString spannable = new SpannableString(text);
        spannable.setSpan(typefaceSpan, 0, text.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        return spannable;
    }

}

Why SPAN_EXCLUSIVE_EXCLUSIVE? Shouldn't it be SPAN_INCLUSIVE_EXCLUSIVE?
