FAQ

A: Octal is a base-8 number system that uses the eight digits 0-7. In computing, it is commonly used for file permission settings, data encoding, program debugging, and other scenarios. The ASCII code of each character can be converted to its corresponding octal representation.

A: UTF-8 supports all characters worldwide, including Chinese; ASCII only supports English letters, numbers, and basic symbols; Latin-1 supports Western European language characters. UTF-8 is recommended for broad character support.

A: Octal numbers can only contain the digits 0-7 and may be separated by spaces, commas, line breaks, etc. For example, "110 145 154" or "110,145,154" are both valid formats. The tool will automatically validate the correctness of the input format.

A: The zero-padding option is used to standardize the number of digits in octal numbers. For example, the octal representation of the number 5 is "5"; after padding to 3 digits, it becomes "005", making it easier to align and read. Automatic zero-padding uses 3 digits by default, but you can also choose 4-digit padding or no padding.

A: Chinese characters and special symbols usually occupy multiple bytes in UTF-8 encoding, so they produce multiple octal numbers. For example, the Chinese character "你" is 3 bytes in UTF-8 and will produce 3 octal numbers. This is normal.

A: Uploading text files in formats such as TXT, CSV, and JSON is supported. The tool will process all files according to the currently selected conversion mode. The interface displays previews of the first 20 files, and all processing results are included in the ZIP download package.

A: Quick actions provide convenient format adjustment features: add spaces to separate octal numbers; remove spaces to get a compact format; add commas or line breaks for different separation methods; and validate the format to check data correctness.

A: The tool provides a mode-switching feature, allowing you to convert the conversion results back to verify accuracy. It also provides a format validation feature to check whether the octal numbers are valid. All conversions follow standard ASCII/UTF-8 encoding rules to ensure accurate results.
