Extrange character returned by GetLastError function

Hi Experts,

I am having a problem when I generate a Transfer of Stock by DI API. The problem is related to the message obtained from the GetLastError () function that introduces arabic characters as shown below:

Quantity falls into negative inventory [الرسالة 131-149]

where the text in Arabic reads "message"

Regardless if I set the language by

oCompany.language = SAPbobsCOM.BoSuppLangs.ln_Spanish_La;
//oCompany.language = SAPbobsCOM.BoSuppLangs.ln_English;

and

Thread.CurrentThread.CurrentCulture = new CultureInfo ("es-MX");

at the start of the program the result is the same.

Any idea?

Greetings !!
