Has anyone experience any problems in creating a message using MQMessage class method WriteUTF(string) when the string is greater than 64Kb. It returns error code 2190, in which indicates MQRC_CONVERTED_STRING_TOO_BIG. Does anyone know how to resolve this? (Using MQ Client v6.0)

Language using is C#.

I starting to believe that there is a limitation of 64K. Can anyone vertify.

Because the "wire" format of UTF, that was implemented by Java in its core classes, contains a 2-byte length field.

So one UTF string for every 64kb.

Or no UTF strings in the first place! Just Unicode.
