Supported Text file formats (IdClassification.Text - Text document encoding formats)
- All entries in table below are supported for file format identification.
- 'X' in "Text" column indicates text extraction is supported for the file format.
- 'X**' in "Text" column indicates text extraction is supported BUT binary-to-text filtering is used on partially parsed document records.
- 'X' in "Metadata" column indicates metadata extraction is supported for the file format.
- 'X' in "EmbeddedItem" column indicates embedded item/attachment extraction is supported for the file format.
- 'X' in "ContentHash" column indicates a content hash is supported for the file format (see MD5ContentHash and SHA1ContentHash)
If a file format does not have a supported content extractor that extracts text then, optionally (default), a binary-to-text content extractor will be used to extract UTF-8, UTF-16, Windows-1252, and ASCII from the binary. In many cases, indexable text can be extract from unknown document formats.
File Format Id Enum Value | Text | Metadata | EmbeddedItem | ContentHash | Description |
|---|---|---|---|---|---|
X | Text in 7-bit ASCII encoding (.txt). | ||||
X | Text in Unicode UTF-7 encoding. UTF-7 is not an official Unicode Standard. The Unicode Standard 5.0 only lists UTF-8, UTF-16 and UTF-32. | ||||
X | Text in Unicode UTF-8 encoding. | ||||
X | Text in Unicode UTF-16LE encoding. | ||||
X | Text in Unicode UTF-16BE encoding. | ||||
X | Text in Unicode UTF-32LE encoding. | ||||
X | Text in Unicode UTF-32BE encoding. | ||||
X | Text in Unicode UTF-EBCDIC encoding (No longer a part of Unicode standard). UTF-EBCDIC is meant to be EBCDIC-friendly, so that legacy EBCDIC applications on mainframes may process the characters without much difficulty. | ||||
Text in an 8-bit undetermined or unsupported OEM code page (has high bytes > 128 and no unprintable ASCII characters found in buffer used to identify). | |||||
