Just as the attachment pic, many error like this occured when installing pon, I had to choose ignore them to complete installation,
I still can enter the pon and run it ,but these files didn't intalling into my game folder at last,I checked
I think the error is because some French or Deutsch letters like "é" ,"ü" are not compatible with Asian language windows
Can these letters be instead of common english letters in the future pon patches(maybe 1.03

Just a little help thread from the east~
PS:Same problem I found in AGEOD's AACW, but only at early version I remembered, lastest patch has used english letters to fix it
