This repository contains mapping tables for converting Unicode characters to octal codes that can be used in GMT and PyGMT.

The mapping tables are stored as comma-separated values files with the following columns:

1. Octal code
2. Unicode value (in hexadecimal)
3. Unicode name

The read_mappings.py script can read the mapping tables in the mappings directory and then output in various formats that can be directly embedded in PyGMT source code and documentation.

Usage:

python read_mappings.py charset.txt

Notes:

1. The original mapping files from different sources are in the official directory. Check the official/README.md file for more information.
2. Some octal codes are not assigned to any characters. Here the special Unicode character � (U+FFFD, REPLACEMENT CHARACTER) is assigned.
