VSCode plugin hangs on setting up a connection to IBM i

[andreasweller]

Bug description
While connecting to IBM i the login script gets stuck while copying from Temp file to ifs:

/home/WELLER: LC_ALL=EN_US.UTF-8 system "call QSYS/QZDFMDB2 PARM('-d' '-i' '-t')"
CREATE TABLE QTEMP.O_FQS9Y AS (select cast(LONG_COMMENT as VarChar(200)) LONG_COMMENT from qsys2.sysroutines where routine_schema = 'ILEDITOR' and routine_name = 'CHECKSTMTWRAPPED') WITH DATA;
Call QSYS2.QCMDEXC('CPYTOIMPF FROMFILE(QTEMP/O_FQS9Y *FIRST) TOSTMF(''/tmp/vscodetemp-O_ZgMO1PfL'') MBROPT(*REPLACE) STMFCCSID(1208) RCDDLM(*CRLF) DTAFMT(*DLM) RMVBLANK(*TRAILING) ADDCOLNAM(*SQL) FLDDLM('','') DECPNT(*PERIOD) STRDLM(*DBLQUOTE) STRESCCHR(*STRDLM)')
{
    "code": 0,
    "signal": null,
    "stdout": "",
    "stderr": ""
}

{
    "code": 0,
    "signal": null,
    "stdout": "DB2>",
    "stderr": ""
}

Expected behavior
Connection to system established and ready to work with.

Environment (please complete the following information):

• Extension version 2.17.0
• IBM i OS version V7R4M0

Additional context
This is running on a German system.
We are using CCSID 1141 at job level and DE_DE as locale. in .bashrc we defined:

export LC_ALL=DE_DE
system "chgjob ccsid(1141)"
