"displayBackground" choices display garbled characters in zhCN:

DisplayBackground.lua line 19 -20 change to:

["green"] = ICON_TAG_RAID_TARGET_TRIANGLE3:gsub("^%l", string.upper),
["blue"] = ICON_TAG_RAID_TARGET_SQUARE3:gsub("^%l", string.upper),

tested both enUS and zhCN.

Thank you for the fix. Released with version 2.49.1
