Incorrect schema name in schema report when feature class / schema name begins with number

[sparkliu]

1. Prepare a feature source with feature class name starting with number. For example, feature class with name "0".
2. Use schema report to preview the feature class.
3. You'll find the feature class name turns to "_x30-".

This is because FDO has two encoding way for name: "-x00-" and "_x00-". When a character is the first character, it will use the latter one. Otherwise, it will use the former one. However, schema report only decodes the former one.
