Charset mishandling with fnx.sie.SieFileByType with QT and Cloud

QueryTool PROD 25.0.68

we have a small issue on char mishandling with fnx.sie.SieFileByType with query tool

the [¨] & [°] are not not well decoded.
see for example : “#KONTO 1114 “FRRDSBYGGNADER 100%”
instead of #KONTO 1114 “FÖRRÅDSBYGGNADER 100%”

we refer to this task Handling Swedish SIE files for Fortnox - 3 van sda

run the code below to reproduce:

create or replace table sie_file@inmemorystorage( FinancialYearId number, FinancialYear   number, Result          clob);
insert into sie_file@inmemorystorage (FinancialYearId, FinancialYear, Result)
select 27, 2025, Resultfrom   fortnox.Sie.SieFileByType@fnx(4, 27);
insert into sie_file@inmemorystorage (FinancialYearId, FinancialYear, Result)
select 26, 2024, Resultfrom   Fortnox.Sie.SieFileByType@fnx(4, 26);
create or replace table sie_lines@inmemorystorage as
select
  f.FinancialYearId,
  f.FinancialYear,
  t.line
from   sie_file@inmemorystorage f
join   csvtable(
         passing replace(f.Result, chr(13), '')     -- normalize CRLF → LF
         row delimiter chr(10)
         column delimiter chr(9)                    -- dummy delimiter
         columns line varchar2 position next
       ) t
where  t.line is not null
and    length(trim(t.line)) > 0;
select * from sie_lines@inmemorystorage

Same issue is present with Invantive Cloud
