Description

Hi all,

Context

To continue some enhancement (#1497), and according some "not working tests" (#1502, #1539), here is a Wanted feature:

  • Could you improve Unicode management on PlantUML?

Issues

Especially on:

  • builtin functions (see examples below)

but also on other sides:

Some examples (for builtin functions) to improve

%chr

Contributor guide

Research direction
Examine the failing tests and source code for builtin functions like %chr, %size, %strlen to understand how Unicode is currently handled, then implement improvements for proper Unicode support.
