| Summary | 0001269: Null Characters Break LuaMsg | ||||
| Description | If you send a string containing null characters (which does not terminate the string in Lua) via LuaMsg, anything after the first null character gets received as garbage. This poses problems for transmission of binary data. I'm not sure how easy or hard it is to fix this. Demo widget to come. | ||||

RecvLuaMsg is null-proof, but send isn't. fix on the way. |
