Description Jing Huo 2023-01-04 10:10:04 UTC 
Description of problem:
`file` misdetects sjis encoded cvs file with CRLF line terminators as "DIY-Thermocam raw data".

Version-Release number of selected component (if applicable):
file-5.33-21.el8.x86_64

How reproducible:


Steps to Reproduce:
1.run `file cvs_filename` against a sjis encoded cvs file with CRLF line terminators
2.
3.

Actual results:

# file file-cmd.csv 
file-cmd.csv: DIY-Thermocam raw data (Lepton 2.x), scale 38590-38590, spot sensor temperature -0.294423, color scheme 150, maximum point enabled, calibration: offset -0.000000, slope 7916750543304341681668233308762275840.000000

Expected results:

# file file-cmd.csv 
file-cmd.csv: Non-ISO extended-ASCII text, with CRLF line terminators


Additional info:
On both RHEL 7 and RHEL 9, `file` can recognize the file correctly.

On RHEL 8, after converting to UTF8, the result is expected.

# file file-utf8.csv 
file-utf8.csv: UTF-8 Unicode text, with CRLF line terminators

After removing CRLF by dos2unix, the result is expected.

# file file-cmd.csv 
file-cmd.csv: Non-ISO extended-ASCII text
