wallet/localization.cpp

Fixing window switches within the frame 
Painfully discovered that wxWidgets does not like it
if you do not handle the close event.  Default
handling is broken, perhaps unavoidably because the base
object does not know about the derived object.

Raw Blame History

// Everything that will need translation should be in localization.cpp
// But this task is barely begun, there are no end of English language
// strings strewn at random about the program which need to be moved to
// localization.h and localization.cpp
// Microsoft Windows, the Visual Studio Compiler, wxWidgets,
// and C++17 onwards is layer after layer of workarounds for the
// localization problem. Mutually conflicting workarounds that
// keep fouling each other up. The final solution to these problems
// is utf-8 and UTF16, and to make it work, you need wallet.manifest
// which gives you a UTF8 execution environment on program launch,
// as if we set the code page in the registry to
// Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\CodePage 65001
// Instead of its normal value of 1252
// and the /utf-8 compile option,
// Properties/C++/AdditionalOptions /utf-8
// which gives you a utf-8 compilation and code generation environment.
// with utf8 in effect at all three levels
// wxUSE_UNSAFE_WXSTRING_CONV == 1
// is desirable, because all those automagical string conversions
// will no longer bite you.
// We really should be running with wxUSE_UTF8_LOCALE_ONLY and
// wxUSE_UNICODE_UTF8, but this will require a wholesale rewrite of
// wxWidgets to use the windowsA calls rather than the windowsW calls,
// albeit this could largely be accomplished by redefining the windows
// macros to default to windowsA where at present they default to windowsW
#include <string>
#include "ILog.h"
#include "localization.h"
// I intend that the download pages will in a location related to the git
// repository, and that when we support multiple languages, the end user will
// download the executable for his language, that we will build a complete
// executable and complete install for every language supported.
// Since the network environment is utf-8, if the locale is not utf-8
// your program has to keep track of two kinds of strings, which it
// will not do successfully. So, forcing environment to utf with
// a windows manifest and a unit test environment check.
// Nearly all of these strings, all of them right now, are seven bit ascii,
// so unicode does not matter but it did a short time ago, and when we get
// around to localization, providing several versions of the localization
// file in several languages, it will matter again.
// No intent to support non UTF-8 locales anywhere in the code.
// code is intentionally written to break on such locales.
// No intent to support local date formats.
// All dates and times shall be YYYY-MM-DD_HH:mm:ss (international format)
// Local date formats are always ambiguous. Date localization is dangerous
// in a program intended to support promises and contracts.
/*
Intended usage is that we have a different download, a different
separately compiled complete program for every locale, with a different
locale.cpp file and all the other files unchanged, rather than trying
to make a single compiled program work in a variety of locales.
At present, there is only one locale.cpp, and if you have a better
solution for supporting multiple locales, you are probably better
qualified at supporting multiple locales than I am.
However my experience is that all the terribly clever solutions for
supporting multiple locales with a single compiled program are fragile
and break every time they issue a new skew of the operating system.
I don't trust them, and are not interested in learning about them.*/

// If non shortest forms are allowed, the attacker can potentially
// cause unexpected code paths to be taken, resulting in consequences
// the programmer did not plan for.
// And, similarly, who knows what may happen if illegally large code points
// are allowed, though I think they were stupid to set a max character limit.
