             Summary: NIFI SFTP processors fails to read filenames NBSP character in name
                 Key: NIFI-15689
                 URL: https://issues.apache.org/jira/browse/NIFI-15689
             Project: Apache NiFi
          Issue Type: Improvement
    Affects Versions: 1.28.1
            Reporter: Franklinsam Paul


When the filename has NBSP list and fetch data using ListSFTP and FetchSFTP processors, which is causing the FetchSFTP processor fails

Environment and details:
- NiFi Version: 1.28.1
- OS / SFTP source: Windows (ACP 1252), LCID 1033
- Processors: ListSFTP → FetchSFTP → ...
- NiFi JVM encoding: UTF-8 (default)
- Symptoms:
  - Files with ASCII characters, spaces, and EN DASH (–) are fetched successfully.
  - Files containing NBSP fail with “file not found” errors in FetchSFTP.
  - Other non-ASCII characters like soft hyphen, ZWSP, RLM may or may not work depending on encoding.

Example:
- Filename: Invoice\u00A0March.csv (NBSP between words) - Windows-1252 encoded
- Hex: 49 6E 76 6F 69 63 65 C2 A0 4D 61 72 63 68 2E 63 73 76
- FetchSFTP cannot locate this file; normal spaces (20) work fine.
