These are the only text flags I could find:
https://github.com/stoneharry/Spell-...s/TextFlags.cs
Code:
namespace SpellEditor.Sources.Constants
{
enum TextFlags : uint
{
EMPTY = 0xFF01FC,
NOT_EMPTY = 0xFF01FE,
// Schlumpf: found a localization flag not being one of the two you know but 0xFF01CC,
// making bit 2 the "is present" bit and adding bits 5 and 6 to the set of unknown ones.
UNKNOWN_1 = 0xFF01CC,
UNKNOWN_2 = 0xFF01EE
}
}
It appears the field is not even read by the client. Each of the other localisation columns is a different language, with only the first ~8 used by retail. As of Cataclysm they stopped localising in this manner and just distributed the files each client needs.
