What are common autocrlf issues?

Common issues related to the core.autocrlf setting in Git include:

Mixed Line Endings: If team members use different settings (e.g., some use true and others use input or false), it can lead to files having mixed line endings, causing problems in collaboration.
Unexpected Changes: When files are checked out or committed, unexpected changes in line endings can occur, leading to large diffs in version control, making it hard to track actual code changes.
Build Failures: Some build tools or scripts may fail if they encounter unexpected line endings, especially if they are sensitive to line endings (e.g., shell scripts on Unix).
File Corruption: If binary files are mistakenly treated as text files due to incorrect autocrlf settings, it can lead to file corruption.
Inconsistent Behavior: Developers working on different operating systems may experience inconsistent behavior if the core.autocrlf setting is not uniformly applied across the team.

To mitigate these issues, it's important to establish a consistent core.autocrlf setting across the team and to use .gitattributes to specify line ending handling for specific files.
