* Character Encoding: Vocaloid 2 uses a specific character encoding. If you're typing in a different encoding, the software might not recognize the characters correctly. This can happen if you're copying and pasting from a different source, or if you're using a different language setting on your computer.
* Font Support: Make sure you're using a font that supports the characters you're using. Some fonts might not include all the characters needed for Japanese writing, including romaji, hiragana, and katakana.
* Software Limitations: Vocaloid 2 is an older software, and it might have limitations when it comes to supporting certain character sets. It might not be able to recognize all the characters you're using, especially if they're from a newer or less commonly used encoding.
* Unsupported Characters: Vocaloid 2 might not recognize certain characters, especially if they are not commonly used in Japanese writing. For example, some special characters or characters from other languages might not be recognized.
* Copypasta Format: While "copypasta" might be a term used to refer to text, it doesn't necessarily indicate a specific format or character encoding. If the copypasta contains characters that are not supported by Vocaloid 2, it might not recognize them correctly.
Here are some things you can try to resolve this issue:
1. Save your lyrics as a plain text file (.txt) with UTF-8 encoding. This will ensure the characters are saved in a format that Vocaloid 2 can understand.
2. Use a font that supports Japanese characters. You can try using a font like "MS Mincho" or "Meiryo UI," which are known to support Japanese characters well.
3. Make sure your computer's language settings are set to Japanese or a compatible language. This will help ensure that the software is using the correct character encoding.
4. Avoid using special characters or characters from other languages. Stick to standard Japanese characters (hiragana, katakana, romaji) for the best compatibility.
5. Check the software's documentation or online forums for more information on supported character sets. There might be specific instructions or workarounds for using different character encodings with Vocaloid 2.
If you're still having trouble, it might be worth considering upgrading to a newer version of Vocaloid, which may have better support for different character sets.
