I use some some czech character in phone config file: Example:
<Default_Character_Encoding ua="na">UTF-8</Default_Character_Encoding> <!-- options: ISO-8859-1/UTF-8 -->
<XML_Directory_Service_Name ua="na">Centrální adresář</XML_Directory_Service_Name>
And it works ok in FW 7.4.8a on display is correct czech chars "Centrální adresář", but not works in 7.4.9a 7.9.4c and new 7.5.1a too. It shows something as "CentrÅilnå_ adres~aiÅ>)"
Is some solution how to fix this ?
It is firmware bug. ISO-8859-1 encoding is used ignoring Default_Character_Encoding value.
You can encode "Centrální seznam" as workaround instead.
But my recommendation is simple: just stay away from national characters at all.
This is not not solution, our customers want full czech support, phone have UTF-8 characters in czech menu ok, in xml ok, only string from provisioning is bad. It was completly ok in older FW. Now we have 7.5.3 FW and it still have same problem. Cisco support for their products is horrible.
Well the problem persists in 7.5.4. Staying away from national characters in a good joke, it's 21st century, wake up!
For us myself included? No, except for yelling at Cisco. I was just bitten by this, new phones came with 7.5.4;(
It may help in the future.
But you denounced advice that is applicable today, so I wished you know something better I can do just now.
