symbol has problem in standard keyboard [BUG]

[Monirzadeh]

What is the problem?
Problem i use standard keyboard in linux and try to work with your pakage
when i run bellow line i get data from database (i just copy that from Readme)

stock = Stocks.query.filter_by(name='كگل').first() #find by symbol(نماد)
stock.df 

but if i type that with Persian standard keyboard i can't get data

stock = Stocks.query.filter_by(name='کگل').first() #find by symbol(نماد)
stock.df 

Why that happen?
if you use this site to check ASCII of 'كگل' (save on database)'کگل' (standard keyboard) you found this is different and because of that you can't request data from database
