pgAdmin4 loses the file format

[yxq]

Hello,   In Windows, after modifying and saving the script in pgadmin4, the 
appropriate end-of-line characters and the BOMB-sign are lost.   Example:  In 
pgadmin4, I opened a file that is in UTF-8 format, Windows end-of-line 
characters (CR LF). The file starts with BOMB characters (script-before.sql)  
After modifying and saving the script (Alt-S), the file no longer has a BOMB 
character, and the end-of-line characters are LF (script-after.sql).   Regards,
