char type and string maniuplation

[chadsec1]

This pull request adds support for a char type, which is the same char type Rust use, which is guaranteed to always be valid UTF-8.

Only new node is CharLiteral.

And as usual, the PR requests accompanies new unit-tests for char type, and misc bug fixes in general around parser, semantics, transpiler, etc.

Pull Request Overview

The PR titled 'char type and string maniuplation' is currently empty and does not contain any code changes. Although the intent summary indicates the introduction of a Rust-style char type and various compiler bug fixes, the diff provides no implementation for the char type, the CharLiteral AST node, or the promised unit tests. As a result, all acceptance criteria are unaddressed. This PR should not be merged until the code changes are properly included.

About this PR

• The PR claims to include miscellaneous bug fixes in the parser, semantic analyzer, and transpiler, but without a diff, the scope and impact of these fixes cannot be evaluated.
• The PR description mentions the addition of 'new unit-tests', but no test files or modifications were included in the diff.
• The PR contains no code changes. The implementation of the char type, CharLiteral AST node, and various bug fixes mentioned in the description are missing from the submission.

Test suggestions

• Parsing of valid UTF-8 character literals
• Validation of multi-byte UTF-8 characters within a char literal
• Semantic analysis and type-checking of char types
• Transpilation of char types to the target language

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Parsing of valid UTF-8 character literals
2. Validation of multi-byte UTF-8 characters within a char literal
3. Semantic analysis and type-checking of char types
4. Transpilation of char types to the target language
