Non-UTF-8 Text File Reading in Go
Problem:
While the standard Go library assumes UTF-8 encoding for all text files, a need arises to read files encoded in other formats, such as GBK. How can this be achieved?
Solution:
Instead of using third-party packages that require cgo and wrap external libraries, Go offers a native solution through its sub-repositories. The golang.org/x/text/encoding package provides an interface for generic character encodings.
Specifically, the golang.org/x/text/encoding/simplifiedchinese sub-package offers implementations for GB18030, GBK, and HZ-GB2312 encodings. By using these encodings, developers can read and write files encoded in GBK seamlessly.
An example showcasing this process involves creating an io.Reader and an io.Writer that perform the encoding and decoding on the fly while reading or writing data. This allows for efficient and transparent handling of non-UTF-8 files.
The above is the detailed content of How Can I Read Non-UTF-8 Encoded (e.g., GBK) Files in Go?. For more information, please follow other related articles on the PHP Chinese website!

Go's "strings" package provides rich features to make string operation efficient and simple. 1) Use strings.Contains() to check substrings. 2) strings.Split() can be used to parse data, but it should be used with caution to avoid performance problems. 3) strings.Join() is suitable for formatting strings, but for small datasets, looping = is more efficient. 4) For large strings, it is more efficient to build strings using strings.Builder.

Go uses the "strings" package for string operations. 1) Use strings.Join function to splice strings. 2) Use the strings.Contains function to find substrings. 3) Use the strings.Replace function to replace strings. These functions are efficient and easy to use and are suitable for various string processing tasks.

Go uses the "encoding/binary" package for binary encoding and decoding. 1) This package provides binary.Write and binary.Read functions for writing and reading data. 2) Pay attention to choosing the correct endian (such as BigEndian or LittleEndian). 3) Data alignment and error handling are also key to ensure the correctness and performance of the data.

Go's bytes package is mainly used to efficiently process byte slices. 1) Using bytes.Buffer can efficiently perform string splicing to avoid unnecessary memory allocation. 2) The bytes.Equal function is used to quickly compare byte slices. 3) The bytes.Index, bytes.Split and bytes.ReplaceAll functions can be used to search and manipulate byte slices, but performance issues need to be paid attention to.

The byte package provides a variety of functions to efficiently process byte slices. 1) Use bytes.Contains to check the byte sequence. 2) Use bytes.Split to split byte slices. 3) Replace the byte sequence bytes.Replace. 4) Use bytes.Join to connect multiple byte slices. 5) Use bytes.Buffer to build data. 6) Combined bytes.Map for error processing and data verification.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
