1.8G日志文件，UTF-8模式可以打开，GBK模式打不开

zufuliu commented 11 months ago

When loading file as GBK (or other encoding other than UTF-8 or ANSI), Notepad2 converts document content from GBK to UTF-16, then UTF-16 to UTF-8, due to the limitation of MultiByteToWideChar() and WideCharToMultiByte(), it's may fails when file size is near 2GB. https://github.com/zufuliu/notepad2/blob/90dfbf8f6370b2410a692cdab092ff190e234e48/src/Edit.h#L423-L424

You can use menu File -> Reload -> As ANSI to reload the file with ANSI (GBK in your case) encoding.

Unckeck "Open ANSI (unknown encoding) files in UTF-8 mode." (from menu File -> Encoding -> Default...) should speedup loading ANSI files. image
