problem

1. fill out the title. when i use my phone, phone input automatically leaves a whitespace after a word. if i dont remove that trailing whitespace...
2. use the "copy to all" function. titles are autonumbered like

File:Title  01.jpg

there will now be 2 whitespaces. 1 is the trailing left by my input. 1 is inserted by uploadwizard.

solution
remove all trailing whitespaces, half-width or full-width, before "copy to all" the title.
