uniscribe | Describe the Unicode [version] [travis]

Describes Unicode characters with their name and shows compositions.

  • Helps you understand how glyphs and codepoints are structured within the data
  • Gives you the names of glyphs and codepoints, which can be used for further research
  • Highlights invalid/special/blank codepoints

Uses a similar color coding like its lower-level companion tool unibits.

Setup

Make sure you have Ruby installed and installing gems works properly. Then do:

$ gem install uniscribe

Usage

Pass the string to debug to uniscribe:

From CLI

$ uniscribe "test strı̈ng"

From Ruby

require "uniscribe/kernel_method"
uniscribe "test strı̈ng"

Output

Notes

Although the gem is generally up to date with Unicode 12.1, the proper detection of compositions / graphemes / combined characters depends on your Ruby version:

Ruby Unicode Version
2.6.3+ 12.1.0
2.6.2 12.0.0
2.6.1- 11.0.0
2.5 10.0.0
2.4 9.0.0
2.3 8.0.0
2.2 7.0.0
2.1 6.1.0

You can run uniscribe -v to check for the Unicode level of your uniscribe version.
