Oracle databases using "UTF8" as the character format for either NCHAR character fields or NCLOB objects are actually using CESU-8 (Compatibility Encoding Scheme for UTF-16: 8-Bit -- for details see https://www.unicode.org/reports/tr26/tr26-4.html). True UTF8 encoding is provided via the AL32UTF8 format.
GemConnect does not currently support CESU-8, and the use of the #UTF8 setting for ncharSet or nclobSet in this configuration will result in typeConversionErrors.
