Bootstrap Table: how to ignore special characters when using filter control column option

I have a bootstrap table where I’ve set my columns to use data-filter-control="select". When I try to filter a column that contains a special character like < or >. It returns No matching records found. However for other characters like &, = or etc. It works fine without any issues. Is there a way to ignore those special characters when using the filter?
