Big Brother is watching you. Or maybe space aliens?

Reload your brain, ask about everything. Our Future begins in... 3... 2... 1... NOW! NB: Better writing with uppercase. Three alternatives (B, F, T) to improve readability in certain cases are in the lowercase. 

~Type an uppercase letter and type the corresponding (or some other) lowercase letter to fill in the shape.

You can use the uppercase letters to form one word and type the lowercase fill letters to form the same or another word, or fill with a blanking glyph to complete the letter with no center letter. So, two types of letters are possible with this one font.

The letters had to be designed such that the uppercase could read as a letter without a center fill on it's own, or filled with blank glyph, or with a center letter. In doing so, the font turned auto-stencil and auto-monospaced. Also, since the unfilled uppercase read as the correct letter with the hole in it, this fs can be said to have three fonts in it.

The gaps are 1/8 brick; the thickness of the inner letter strokes is 2/8 brick. Therefore, this limitation meant that the glyphs with a stroke in the horizontal center can either be lined up with the left side blocks or the right side one. Therefore, 3/8 brick thickness I and T are provided on { and }.

Letter couples are as follows: Aa  Bb  Cc  Dd  Ee  Ff  Gg  Hh  Ii or I{  Jj  Kk  Ll  Mm  Nn  Oo  Pp  Qq  Rr  Ss  Tt or T}  Uu  Vv  Ww  Xx  Yy  Zz

Number couples are: !1  @2  #3  $4  %5  ^6  &7  *8  (9  )0

Blanks: ~, space

Center blank: `

Pipe: = (which will offset the monospacing)

Others; ? is at ?/  ! is at |\

Punctuations are where they are supposed to be: .  ,  ;  :  '  "  ’  ”  ‘  “  -

Sample: Type the following in User Input to see the font as it is supposed to be:  A`AaB`BbC`CcD`DdE`EeF`FfG`GgH`HhI`IiI{J`JjK`KkL`LlM`MmN`NnO`OoP`PpQ`QqR`RrS`SsT`TtT}U`UuV`VvW`WwX`XxY`YyZ`Zz!`!1@`@2#`#3$`$4%`%5^`^6&`&7*`*8(`(9)`)0?`?/|`|\)-)+~_<>=

6 bricks tall.

The sample is a font pun: TWO in ONE.

PS: Not sure how future it is.

Space, the final font-ier
