I have a good jabber-config.xml I edited in Notepad++ and saved (UTF-8) and I upload it to TFTP via CMPlatform on CCM 9.1.2.11900-12. I've done this in the past a lot with 8.6.2, never had any issues.
I then restart CUCM TFTP services and download;
C:\>tftp 10.7.8.3 GET jabber-config.xml
Transfer successful: 2390 bytes in 1 second(s), 2390 bytes/s
I then open up my downloaded jabber-config.xml in Notepad++ and it says the file format is UCS-2 Litle Indian and not UTF-8 and looks like the attached photo. Greek. I tried in Notepad++ to convert.
I then setup a different test PC with Windows XP, etc. Same issue, also note that plain notepad sees the same problem. Why is the jabber-config.xml file getting corrupted by the TFTP server?
