# Why is only one letter of this font displaying?

GotIn.fd is a decorative initial font created by Dieter Steffman. It can be found on CTAN here. While drafting, I've been experimenting with numerous decorative initial fonts found at this archive. A number of them work as expected. EG

% ...within the preamble...
\input{Typocaps.fd}

% ...later in the document...
{\Huge\usefont{U}{Typocaps}{xl}{n}Check out this cool font!}\\


produces this output:

This is not the case with GotIn.fd. EG:

% ...within the preamble...
\input{GotIn.fd}

% ...later in the document...
{\Huge\usefont{U}{GotIn}{xl}{n}Check out this cool font!}\\


produces this output:

I am not clear what is going on here. Numerous other fonts from the same archive work as intended. A number of them last updated well before GotIn.fd. Maybe a more experienced LaTeX user can speak to this.

P.S., I'm using overleaf.

• Probably the font has only uppercase letters. May 8 '20 at 0:40
• Confirmed that by examining the font in FontForge (fontforge.org/en-US). May 8 '20 at 0:44
• Welcome to TeX.SE. We generally prefer to work with "minimal working examples", so that we can copy/paste and immediately see what you're talking about. In this case, I think that just means adding \documentclass{article} ... \begin{document} ... \end{document}. May 8 '20 at 2:06

@Thérèse was correct in their comment. The font requires the inputted characters be uppercase. Adjusting the code to be such:

% ...within the preamble...
\input{GotIn.fd}

% ...later in the document...
{\Huge\usefont{U}{GotIn}{xl}{n}CHECK OUT THIS COOL FONT!}\\


outputs the desired result. Thank you!

• Suggestion: Always put \tracinglostchars=2 in all your TeX files, especially when fiddling with fonts: otherwise the warning message about missing characters in fonts appears only in the log file. (A design flaw in TeX IMO: it should have been possible to make it a fatal error.) May 8 '20 at 2:39
• Thanks for the tip! I'm certain this should be a default feature when using the [draft] option. May 8 '20 at 3:07
