Personal Finance Whitepaper

An IEEE two-column academic whitepaper on the three-pillar personal-finance system, by Nonthawit Doungsodsri (nonthawit.com).

Editions

Source Output Body font Currency
whitepaper-th.tex ../whitepaper-th.pdf TH Sarabun New, 14pt THB
whitepaper-en.tex ../whitepaper-en.pdf TeX Gyre Termes, 10pt USD
whitepaper-es.tex ../whitepaper-es.pdf TeX Gyre Termes, 10pt EUR
whitepaper-id.tex ../whitepaper-id.pdf TeX Gyre Termes, 10pt IDR
whitepaper-zh.tex ../whitepaper-zh.pdf Noto Serif CJK SC, 11pt CNY
whitepaper-ja.tex ../whitepaper-ja.pdf Noto Serif CJK JP, 11pt JPY

Every font is bundled in fonts/, so the build is self-contained and needs no system-installed fonts. The CJK editions also set TeX Gyre Termes for their Latin text.

Prerequisites

tectonic — the XeTeX engine that compiles these documents and auto-fetches any LaTeX packages it needs:

brew install tectonic

Build

./build.sh

build.sh compiles each edition from the latex/ directory (so the bundled fonts/ resolve) and writes every PDF to the project root.

Fonts

fonts/ holds the bundled faces:

  • THSarabunNew-*.ttf — Thai (SIPA national font).
  • texgyretermes-*.otf — Times-compatible Latin (GUST Font License).
  • NotoSerifCJKsc-*.otf, NotoSerifCJKjp-*.otf — Chinese / Japanese (SIL OFL). These are subset to the glyphs each document uses, keeping them small.

Notes

  • Every document is monochrome — all text is black.
  • The Thai edition uses XeTeX's ICU line-break locale; it requires the XeTeX engine (pdflatex will not work).
  • The example figures use each region's local currency with round illustrative numbers.

The bundled fonts in fonts/ are third-party and licensed separately (SIL OFL, GUST Font License, SIPA) — see fonts/LICENSES/NOTICE.md. The MIT License does not apply to them.

Adding a language

Copy the closest existing .tex, translate the body, set the currency, point \setCJKmainfont at a bundled CJK face if needed, and add the language stem to the editions array in build.sh. For a new CJK script, drop its font in fonts/ and subset it after the text is final.
