Blob Storage (1 / 24): You are developing a service that organizes uploaded documents into containers in Azure Blob Storage. Your application assigns metadata to each container, including user names and titles that may contain international characters (e.g., Vietnamese or Bulgarian diacritics). You use the SetMetadata method on a BlobContainerClient to store this metadata. During testing, you discover that the metadata appears corrupted or incomplete when retrieved. You need to ensure the metadata is stored and retrieved correctly without losing any special characters.
What should you do?
Answer:
Azure Storage metadata only supports ASCII characters. If you need to store non-ASCII characters (e.g., Unicode), you must encode them, and Base64 is the standard workaround.
