Change "coding" to "encoding"
I see both "coding" and "encoding" being used.
Maybe change "coding" to "encoding" in there two strings:
Character c_oding to use:
Ch_aracter coding to use:

In help there are these strings:
"Character coding a subtitle format auto-detection (on opening)"
"If you want to specify the file's character coding, choose one from the " "Character Coding list. If not specified, the caracter coding will be auto " "detected."
"caracter" is also misspelled.
