Qwigley: Missing Unicode characters U+011E, U+011F and U+0130

**Describe the bug**

While using the Qwigley font in Unity 6 (TextMeshPro), I noticed that the Unicode characters **ğ (U+011F)**, **Ğ (U+011E)**, and **İ (U+0130)** are not available in the generated TextMeshPro Font Asset. As a result, these characters cannot be displayed correctly in Unity.

Other Latin Extended characters, such as **Ş (U+015E)** and **ş (U+015F)**, are generated correctly, while only **ğ (U+011F)**, **Ğ (U+011E)**, and **İ (U+0130)** are affected.

Would you consider adding proper support and correct character mappings for these three Unicode characters to the font? I believe this would significantly improve compatibility with software that relies on Unicode character mappings, such as Unity TextMeshPro, and provide more complete support for Latin Extended characters.

**To Reproduce**

1. Open Unity 6.
2. Create a TextMeshPro Font Asset using `Qwigley-Regular.ttf`.
3. Include **U+011E**, **U+011F**, and **U+0130** in the character set (or use a Unicode range that includes them).
4. Generate the Font Asset.
5. The three characters are not included in the generated Font Asset and cannot be rendered correctly.

**Expected behavior**

The Unicode characters **ğ (U+011F)**, **Ğ (U+011E)**, and **İ (U+0130)** should be included in the generated TextMeshPro Font Asset and render correctly in Unity TextMeshPro and other software that relies on Unicode character mappings.

**Additional context**

First of all, thank you for creating such a beautiful font. Qwigley is one of my favorite handwritten fonts.
