What is difference between "unicharset file" and "lstm-unicharset file"

[이경준]

Hi . Thank you for seeing my questions 

1. What is difference between 'unicharset' and 'lstm-unicharset' ?  

I know to make 'unicharset' by command line : "$ tesseract (lang).(filename).exp(num).tif  (lang).(filename).exp(num).box

But I don't know to make 'lstm-unicharset'  ???

cf) .tr -> .lstmf

I apply this command line = "$tesseract (lang).(filename).exp(num).tif (lang).(filename).exp(num) nobatch box.train" to tesseract (lang).(filename).exp(num).tif (lang).(filename).exp(num) nobatchlstm.train"

2. This usage is right? 

Is it possible to apply 'unicharset' to 'lstm-unicharset'

3. In the github wiki passage

Overview of Training Process

The overall training process is similar to training 3.04.

Conceptually the same:

1. Prepare training text.
2. Render text to image + box file. (Or create hand-made box files for existing image data.)
3. Make unicharset file. (Can be partially specified, ie created manually).
4. Make a starter traineddata from the unicharset and optional dictionary data.
5. Run tesseract to process image + box file to make training data set.
6. Run training on training data set.
7. Combine data files.

The key differences are:

• The boxes only need to be at the textline level. It is thus far easier to make training data from existing image data.
• The .tr files are replaced by .lstmf data files.
• Fonts can and should be mixed freely instead of being separate.
• The clustering steps (mftraining, cntraining, shapeclustering) are replaced with a single slow lstmtraining step.

I think that In The key differecen section "unicharset" are replace by "lstm-unicharset"  - sentence is added 

Am I false???? 

I wait everybody's answers

Thank U. Have a nice day!
