Following raylib design, a warning log message is shown and program can continue execution.
Some early return checks have been added on most  critical functions.
[rtext] Previous implementation checking `isGpuReady` cross-module variable is not needed any more, resulting in a more decoupled code, load failure is managed at rlgl level

- REVIEWED: Checking `NULL` input on functions getting `const char *text`, to avoid crashes
- REVIEWED: `strcpy()` usage, prioritize `strncpy()` with limited copy to buffer size
- REPLACED: `strlen()` by `TextLength()` on [rtext] module
- REVIEWED: Replaced some early returns (but keeping others, for easier code following)

Specifically "occured" -> "occurred"

* Get C++ compilers working

* Fix Formatting

 - char *TextReplaceBetween(const char *text, const char *begin, const char *end, const char *replacement); // Replace text between two specific strings (WARNING: memory must be freed!)

This reverts commit 4e8d08523f.

* add const qualifier to the first arg of TextJoin

* Update raylib_api.* by CI

* Update raylib.h

This redesign is a big improvement on font loading time and memory requirements. It only loads glyphs available on font from requested codepoints and only processes those glyphs for packaging. When processing +10K codepoints (CJK), the loading time improves considerably.

Make the default font loader early out if we have already loaded parts of it, so we don't leak memory

Fix buffer write overflow
Fix reading past the end of text

I was really wondering what is going on here :D I believe this code
tried initially to out-cast 'const' specifier but this is not needed here
at all. Currently, it just confuses whoever reads this so I changed it.
The old code would also trigger -Wcast-qual warning on some compilers.

It generates multiple issues: https://c-faq.com/ansi/constmismatch.html

Lately got some compilation `errors` related, it seems GCC 14 interprets some `const`-missmatch as errors instead of warnings (as previous versions).

But in any case, I don't see why an user won't be able to operate directly over of those returned buffers; `const` adds a restriction (for security reasons?) that in my opinion is useless.

From an expert on compilers (w64devkit creator), here there are some notes I agree with:

```
No const. It serves no practical role in optimization, and I cannot recall an instance where it caught, or would have caught, a mistake. I held out for awhile as prototype documentation, but on reflection I found that good parameter names were sufficient. Dropping const has made me noticeably more productive by reducing cognitive load and eliminating visual clutter. I now believe its inclusion in C was a costly mistake.

(One small exception: I still like it as a hint to place static tables in read-only memory closer to the code. I’ll cast away the const if needed. This is only of minor importance.)
```
