Description
🌟 Feature Description
对于字符串特征直接存储字符串的原始值。不需要预编码成整数。
Motivation
- Application scenario
对于深度模型来说，直接把字符串映射到一个emb，应该会比把字符串编码成整数再映射到emb，会省一些内存。对于一些新闻文本来说，直接由模型来学习文本向量会更加端到端。目前的qlib似乎不支持string类型的特征。这个是否能够添加支持。

Research direction
The issue names no files, tests, or entry points. First clarify which Qlib feature-storage and model-input paths must accept raw strings, then inspect the existing feature representation and encoding flow. Done means string-valued features are supported end to end and the relevant behavior is covered by tests.
