Be careful when using Unicode mode with String type variables. When Unicode mode is active String types are the same as their respective Text types, however the constants do not change to reflect this behavior. Examples are shown below.

In compatibility mode:

SET DATABASE PARAMETER(41;0) $unicodeMode:=Get database parameter(41) C_TEXT($textVar) _o_C_STRING(30;$stringVar) ARRAY TEXT($textArray;0) _o_ARRAY STRING(30;$stringArray;0) $textVar_Type:=Type($textVar) $stringVar_Type:=Type($stringVar) $textArray_Type:=Type($TextArray) $stringArray_Type:=Type($StringArray) Is text Is string var Text array String array TRACE

As seen, the variables' types and constansts match each other as expected when unicode mode is disabled.

In unicode mode:

SET DATABASE PARAMETER(41;1) $unicodeMode:=Get database parameter(41) C_TEXT($textVar) _o_C_STRING(30;$stringVar) ARRAY TEXT($textArray;0) _o_ARRAY STRING(30;$stringArray;0) $textVar_Type:=Type($textVar) $stringVar_Type:=Type($stringVar) $textArray_Type:=Type($TextArray) $stringArray_Type:=Type($StringArray) Is text Is string var Text array String array TRACE

However, with unicode mode enabled, String types are changed to the same as Array types, and do not match their constants.
