### Motivation

   * #sizeIfKnown}, returning true if it's known to be zero and false if it's known to be non-zero.
   * If the size is not known, it falls back to opening a stream and checking for EOF.
   *
   * <p>Note that, in cases where {@code sizeIfKnown} returns zero, it is <i>possible</i> that bytes
   * are actually available for reading. (For example, some special files may return a size of 0

### Naming Convention

- **Language only**: `fess_label_en.properties`, `fess_label_ja.properties`
- **Language + Region**: `fess_label_pt_BR.properties`, `fess_label_zh_CN.properties`, `fess_label_zh_TW.properties`
- **Special cases**: Kurdish uses `fess_label_ckb_IQ.properties`

## Step-by-Step Guide

### 1. Create Language Resource Files

Copy the base English files as templates:

```bash
cd src/main/resources
