Problem Description

When a user's name is registered in Korean (or other non-Latin characters), file upload operations fail with a UnicodeEncodeError. The error occurs in the embedding generation process when the ENABLE_FORWARD_USER_INFO_HEADERS setting is enabled.

Error Details:

UnicodeEncodeError: 'latin-1' codec can't encode characters in position 0-2: ordinal not in range(256)

Root Cause:
The issue stems from the HTTP header encoding limitation where the X-OpenWebUI-User-Name header is set with non-ASCII characters (Korean name "테스터" in this case). HTTP headers must be encoded in Latin-1, but Korean characters cannot be represented in this encoding scheme.

Steps to Reproduce:

1. Enable ENABLE_FORWARD_USER_INFO_HEADERS setting
2. Register a user with a Korean name (e.g., "테스터")
3. Attempt to upload a file
4. The operation fails with the Unicode encoding error

Error Stack Trace Key Points:

• Error occurs in urllib3/connection.py at line 358: super().putheader(header, *values)
• The header X-OpenWebUI-User-Name contains Korean characters that cannot be encoded in Latin-1
• This causes a cascading failure in the embedding generation process

Desired Solution you'd like

Primary Solution:
Fix the Unicode encoding issue by implementing proper encoding for non-ASCII characters in HTTP headers. The system should handle international character sets in user names when setting the X-OpenWebUI-User-Name header value. Please investigate appropriate encoding methods that comply with HTTP header standards while preserving the original user name information.

Alternative Solution:
If the primary fix is complex to implement, provide more granular control over the ENABLE_FORWARD_USER_INFO_HEADERS setting by adding a new configuration option that allows users to specify which headers to forward:

FORWARD_USER_INFO_HEADERS = ["X-OpenWebUI-User-ID", "X-OpenWebUI-User-Email"]  # Exclude User-Name

This would allow users to forward user information without including problematic headers that contain non-ASCII characters.

Expected Behavior:

• Users with non-ASCII names should be able to upload files without encountering encoding errors
• The user information should be properly forwarded to downstream services when the header forwarding feature is enabled
• The system should gracefully handle international character sets in user names

Originally created by @dulicon on GitHub (May 27, 2025). Original GitHub issue: https://github.com/open-webui/open-webui/issues/14375 ### Check Existing Issues - [x] I have searched the existing issues and discussions. ### Problem Description When a user's name is registered in Korean (or other non-Latin characters), file upload operations fail with a `UnicodeEncodeError`. The error occurs in the embedding generation process when the `ENABLE_FORWARD_USER_INFO_HEADERS` setting is enabled. **Error Details:** ``` UnicodeEncodeError: 'latin-1' codec can't encode characters in position 0-2: ordinal not in range(256) ``` **Root Cause:** The issue stems from the HTTP header encoding limitation where the `X-OpenWebUI-User-Name` header is set with non-ASCII characters (Korean name "테스터" in this case). HTTP headers must be encoded in Latin-1, but Korean characters cannot be represented in this encoding scheme. **Steps to Reproduce:** 1. Enable `ENABLE_FORWARD_USER_INFO_HEADERS` setting 2. Register a user with a Korean name (e.g., "테스터") 3. Attempt to upload a file 4. The operation fails with the Unicode encoding error **Error Stack Trace Key Points:** - Error occurs in `urllib3/connection.py` at line 358: `super().putheader(header, *values)` - The header `X-OpenWebUI-User-Name` contains Korean characters that cannot be encoded in Latin-1 - This causes a cascading failure in the embedding generation process ### Desired Solution you'd like **Primary Solution:** Fix the Unicode encoding issue by implementing proper encoding for non-ASCII characters in HTTP headers. The system should handle international character sets in user names when setting the `X-OpenWebUI-User-Name` header value. Please investigate appropriate encoding methods that comply with HTTP header standards while preserving the original user name information. **Alternative Solution:** If the primary fix is complex to implement, provide more granular control over the `ENABLE_FORWARD_USER_INFO_HEADERS` setting by adding a new configuration option that allows users to specify which headers to forward: ```python FORWARD_USER_INFO_HEADERS = ["X-OpenWebUI-User-ID", "X-OpenWebUI-User-Email"] # Exclude User-Name ``` This would allow users to forward user information without including problematic headers that contain non-ASCII characters. **Expected Behavior:** - Users with non-ASCII names should be able to upload files without encountering encoding errors - The user information should be properly forwarded to downstream services when the header forwarding feature is enabled - The system should gracefully handle international character sets in user names ### Alternatives Considered _No response_ ### Additional Context Server logs when the error occurred are attached below for reference. ``` 2025-05-27 04:40:04.356 | INFO | open_webui.routers.retrieval:save_docs_to_vector_db:969 -
