You have described that a character may be represented by 4 bytes, but that does not really answer my question. That upper limit would apply if a string holding MPD_PATH_MAX 4-byte characters must be represented. When will that happen? What is the real meaning of this MPD_PATH_MAX_UTF8 value, in general? Is it an upper limit imposed by MPD? By the operating system? What will it be used for? I'm asking specifically because on Linux, the name limit is not measured by number of characters, but by number of bytes. That is because the kernel does not know or care about "characters". On Linux, this constant doesn't make a lot of sense, and I'm trying to imagine a use case where it would make sense. What I don't want is some obscure constant floating around in a header file that people will start to use without understanding the math behind it. ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
