+Now it is time to add our font data to the HII Database.
+
+Initialize new application:
+```
+./createNewApp.sh HIIAddRussianFont
+```
+Add it to the package DSC file (UefiLessonsPkg/UefiLessonsPkg.dsc):
+```
+[Components]
+  UefiLessonsPkg/HIIAddRussianFont/HIIAddRussianFont.inf
+```
+
+In our application we would populate package list to the HII database, so we need to declare GUID for this package list in the `UefiLessonsPkg/UefiLessonsPkg.dec`:
+```
+[Guids]
+  ...
+  gHIIAddRussianFontGuid = { 0x9fe2f616, 0x323c, 0x45a7, { 0x87, 0xa2, 0xdf, 0xef, 0xf5, 0x17, 0xcc, 0x66 }}
+```
+And declare that our app would need it in the `UefiLessonsPkg/HIIAddRussianFont/HIIAddRussianFont.inf`:
+```
+[Packages]
+  ...
+  UefiLessonsPkg/UefiLessonsPkg.dec
+
+[Guids]
+  gHIIAddRussianFontGuid
+```
+Also we would be using library for HII services (for example for `HiiAddPackages` function), so let's include it from the start:
+```
+[Packages]
+  ...
+  MdeModulePkg/MdeModulePkg.dec
+
+[LibraryClasses]
+  ...
+  HiiLib
+```
+
+# String.uni file
+
+Add strings UNI file to our application sources `UefiLessonsPkg/HIIAddRussianFont/HIIAddRussianFont.inf`:
+```
+[Sources]
+  ...
+  Strings.uni
+```
+
+Then create this `Strings.uni` file with these strings:
+- "Hello!"
+- "Bye!"
+- Language alphabet in uppercase
+- Language alphabet in lowercase
+```
+#langdef en-US "English"
+#langdef fr-FR "Francais"
+#langdef ru-RU "Russian"
+
+#string STR_HELLO               #language en-US  "Hello!"
+                                #language fr-FR  "Bonjour!"
+                                #language ru-RU  "Привет!"
+
+#string STR_BYE                 #language en-US  "Bye!"
+                                #language fr-FR  "Au revoir!"
+                                #language ru-RU  "До свидания!"
+
+#string STR_ALPHABET_UPPERCASE  #language en-US  "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
+                                #language fr-FR  "ABCDEFGHIJKLMNOPQRSTUVWXYZÀÈÙÉÂÊÎÔÛËÏÜŸÆŒÇ"
+                                #language ru-RU  "АБВГДЕЁЖЗИЙКЛМНОПРСТУФХЦЧШЩЬЪЭЮЯ"
+
+#string STR_ALPHABET_LOWERCASE  #language en-US  "abcdefghijklmnopqrstuvwxyz"
+                                #language fr-FR  "abcdefghijklmnopqrstuvwxyzàèùéâêîôûëïüÿæœç"
+                                #language ru-RU  "абвгдеёжзийклмнопрстуфхцчшщьъэюя"
+```
+The alphabet strings would help us to check if all the letters in the language are printed correctly.
+
+# RussianFont.c
+
+Add our file with russian font glyphs that we've recieved in the last lesson to our `UefiLessonsPkg/HIIAddRussianFont/HIIAddRussianFont.inf`:

+```
+Here we:
+- construct font package data from the Glyph arrays from the `RussianFont.c` file. We will define this `CreateSimpleFontPkg` function next,
+- use `HiiAddPackages` to add both font package and application strings package (this function is variadic, it can take variable number of packages and push them all to create the new package list [https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Library/UefiHiiLib/HiiLib.c]),
+- once we've added packages we no longer need `FontPackage`, so don't forget to free it with a `FreePool` function
+- if everything is ok, use `HiiGetString` to print all the strings in all languages,
+
+Now it is time to define our `CreateSimpleFontPkg` function. But first here are the necessary defines and types for the font package creation https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Uefi/UefiInternalFormRepresentation.h:
+```
+///
+/// A simplified font package consists of a font header
+/// followed by a series of glyph structures.
+///
+typedef struct _EFI_HII_SIMPLE_FONT_PACKAGE_HDR {
+  EFI_HII_PACKAGE_HEADER Header;
+  UINT16                 NumberOfNarrowGlyphs;
+  UINT16                 NumberOfWideGlyphs;
+  // EFI_NARROW_GLYPH       NarrowGlyphs[];
+  // EFI_WIDE_GLYPH         WideGlyphs[];
+} EFI_HII_SIMPLE_FONT_PACKAGE_HDR;
+
+///
+/// The header found at the start of each package.
+///
+typedef struct {
+  UINT32  Length:24;
+  UINT32  Type:8;
+  // UINT8  Data[...];
+} EFI_HII_PACKAGE_HEADER;
+
+
+//
+// Value of HII package type
+//
+...
+#define EFI_HII_PACKAGE_SIMPLE_FONTS         0x07
+...
+```
+
+In our function we need to allocate necessary array for the font package. Besides allocating space for the package itself we need to add 4 bytes for the package size that would prepend all the data. As you remember this is the necessary data format for the `HiiAddPackages` function:
+```
+UINT8* CreateSimpleFontPkg(EFI_WIDE_GLYPH* WideGlyph,
+                           UINT32 WideGlyphSizeInBytes,
+                           EFI_NARROW_GLYPH* NarrowGlyph,
+                           UINT32 NarrowGlyphSizeInBytes)
+{
+  UINT32 PackageLen = sizeof(EFI_HII_SIMPLE_FONT_PACKAGE_HDR) + WideGlyphSizeInBytes + NarrowGlyphSizeInBytes + 4;
+  UINT8* FontPackage = (UINT8*)AllocateZeroPool (PackageLen);
+
+  *(UINT32*)FontPackage = PackageLen;
+
+  ...
+
+  return FontPackage;
+}
+```
+
+Now fill the package data. First fill the header:
+```
+EFI_HII_SIMPLE_FONT_PACKAGE_HDR *SimpleFont;
+SimpleFont = (EFI_HII_SIMPLE_FONT_PACKAGE_HDR*)(FontPackage + 4);
+SimpleFont->Header.Length = (UINT32)(PackageLen - 4);
+SimpleFont->Header.Type = EFI_HII_PACKAGE_SIMPLE_FONTS;
+SimpleFont->NumberOfNarrowGlyphs = (UINT16)(NarrowGlyphSizeInBytes / sizeof(EFI_NARROW_GLYPH));
+SimpleFont->NumberOfWideGlyphs = (UINT16)(WideGlyphSizeInBytes / sizeof(EFI_WIDE_GLYPH));
+```
+And then copy the Glyphs data (for the `CopyMem` function you need to include `<Library/BaseMemoryLib.h>` header):
+```
+UINT8* Location = (UINT8*)(&SimpleFont->NumberOfWideGlyphs + 1);
+CopyMem(Location, NarrowGlyph, NarrowGlyphSizeInBytes);
+CopyMem(Location + NarrowGlyphSizeInBytes, WideGlyph, WideGlyphSizeInBytes);
+```
+
+If you build and run our application now, you would see that russian strings are printed correctly:
+
+![AddFont1](AddFont1.png?raw=true "Add font 1")
+
+
+Now let's try to print some string in russian at the beginning and at the end of our application:
+```
+EFI_STATUS
+EFIAPI
+UefiMain (
+  IN EFI_HANDLE        ImageHandle,
+  IN EFI_SYSTEM_TABLE  *SystemTable
+  )
+{
+  Print(L"Привет!\n");
+
+  ...
+
+  Print(L"Привет!\n");
+
+  return EFI_SUCCESS;
+}
+
+First print would produce only `!` as there are no information in the system about how to display russian unicode symbol glyphs. But at the end after we've added our font package, print would produce expected result:
+
+![AddFont2](AddFont2.png?raw=true "Add font 2")
