Re: [wxlua-users] wxString::ToAscii

[Victor B. <so...@te...>]

actually wxMBConv and derived should be implemented because "Lua uses ANSI 8-bit strings" as says the wxLua manual but you can get in them every kind of data : unicode strings or embeded zeros.

So instead of needing require"iconv", wxLua would be enought

  the problem is converting from ANSI to UNICODE

  wxLua unicode build converts as if the string were UTF8 to UNICODE
  it works from code 1 to 127 but fails on 128-255 which are not valid UTF 
  0 is discarded in lua2wx 
      if (luastr == NULL) return wxEmptyString; // check for NULL
  which is a problem for lua strings with embeded ceros

  using AddTextRaw uses the string as an already UNICODE string so 1-255 are visible althought 128-255 dont show ANSI caracters

  So would be ideal to having a function for converting from ANSI to UTF or UTF to ANSI (it depends on the ANSI codepage)

  as in http://docs.wxwidgets.org/trunk/overview_mbconv.html example 1

  (or may be ANSI to UNICODE and UNICODE to ANSI)

    If you are trying to convert to/from UTF8, you may want to check this discussion (http://sourceforge.net/p/wxlua/mailman/message/32175781/) and the methods described in it. See if this helps.
