UI: Fix non-standard string character in source

(Jim) For some reason a character outside of the standard ASCII
character set was used in this source file.  "Eight Spoked Asterisk",
Unicode character 0x02733.  Non-ASCII characters should probably not be
used directly in source files due to potential character encoding
issues that can occur depending on the operating system and compiler.
