printing - Printer function in PHP cannot print Chinese character (UTF-8) -


I use the printer function to print some data in the text file (.txt), which includes Chinese and English words They can display correctly in both webpages, while printing, the English word looks good but the Chinese word does not show the correct output. Any tips to overcome this? Please help me out my coding below. 

  & lt ;? Php $ print = file_get_contents ("print.txt"); $ Printer = "XP-80"; // Printer name resonance print $; If ($ ph = printer_open ($ printer)) {printer_set_option ($ ph, PRINTER_MODE, "RAW"); Printer_write ($ pH, $ print); Print_close ($ pH); }? & Gt; 
 
 
 There are some things that I can think of as a cause of problem:   / P> 
     
  •  The font you select is not compatible with UTF-8. There is also a note about  
  •   printer_set_option () . Since 2009, it is not certain that it is still valid.   
      After you comment, edit:   
     with this example  
      $ font = printer_create_font ("Aerial", 148, 76, PRINTER_FW_MEDIUM, wrong, false, false, -50); Printer_select_font ($ ph, $ font);

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
