70054 - The filename filesrvc does not read a text file correctly under LATIN1 SAS session encoding

Problem Note 70054: The filename filesrvc does not read a text file correctly under LATIN1 SAS session encoding

If you use a program similar to the following to read a files object that contains a text content type (for example, text/plain or text/html) in a LATIN1 SAS session encoding, and you read the files object back in a fixed record format, the text file is not read correctly:

proc options option=encoding;

run;
filename epCode temp;

filename srcEp filesrvc "/files/files/e4bdb952-0c6c-4821-a716-3cb52baa6373";
data _null_;

    infile srcEp length=len recfm=f _infile_=tmp;

    file epCode recfm=n;

    input;

    put tmp $varying32767. len;

run;

If you set the SAS session encoding to LATIN1, you will receive an incorrect number of records and an incorrect file Encoding= value. You could also receive an error that indicates a transcoding problem in the SAS log. The corresponding SAS log looks similar to the following:

82   proc options option=encoding;

83   run;

    SAS (r) Proprietary Software Release V.03.05  TS1M0

 ENCODING=LATIN1   Specifies the default character-set encoding for the SAS session.

NOTE: PROCEDURE OPTIONS used (Total process time):

      real time           0.00 seconds

      cpu time            0.00 seconds

...

104  run;

NOTE: The infile SRCEP is:

      Filename=#LN00006,

      URI path=/files/files/e4bdb952-0c6c-4821-a716-3cb52baa6373,

      File Identifier=e4bdb952-0c6c-4821-a716-3cb52baa6373,

      Content Type=text/plain,

      Parent URI=/jobExecution/jobs/ec7cc5f2-d038-474c-80ec-f692a98251c2,

      Encoding=UTF-8,RECFM=F,LRECL=256,

      File Size (bytes)=4517,

      Last Modified=04Dec2019:16:39:04,

      Create Time=04Dec2019:16:39:04

NOTE: UNBUFFERED is the default with RECFM=N.

NOTE: The file EPCODE is:

      Filename=/opt/sas/viya/config/var/tmp/compsrv/default/0ff60388-dfe0-4fc6-830e-39f31d8c15d2/SAS_work649D0001103B_sasserver.demo

NOTE: 5 records were read from the infile SRCEP.

NOTE: DATA statement used (Total process time):

If the filename filesrvc worked correctly, it should read in 18 records (4517/256=17.64), and the Encoding= value should be ISO_8859-1. Instead, it reads only in 5 records and the Encoding= value is UTF-8.

Note that you can use the following file to check the contents: /opt/sas/viya/config/var/tmp/compsrv/default/0ff60388-dfe0-4fc6-830e-39f31d8c15d2/SAS_work649D0001103B_sasserver.demo.sas.com/#LN00116. However, that file is not the same as the following file: /files/files/e4bdb952-0c6c-4821-a716-3cb52baa6373

To work around this issue, change the SAS session encoding to UTF-8.
