I need the list of ranges of Unicode characters with the property Alphabetic as defined in http://www.unicode.org/Public/5.1.0/ucd/UCD.html#Alphabetic. However,

    Citation from your source: Generated from: Lu + Ll + Lt + Lm + Lo + Nl + Other_Alphabetic

    These Abbrevations seem to be explained here.

    I found the UniView web application which provides a nice search interface. Searching for the Letter property (with Local unchecked) gives 14723 results...

    The Unicode Character Database comprises all the text files in the distribution. It is not just a single file as it once was long ago.

    The Alphabetic property is a derived property.

    You really do not want to use code point ranges for this. You want to use the property properly. That’s because there are just too many of them. Using the unichars script, we learn that there are more than ten thousand just in the Basic Multilingual Plane alone not counting Han or Hangul:

    $ unichars '\p{Alphabetic}' | wc -l
       10052
    

    If we include the other 16 astral planes, now we’re at fourteen thousand:

    $ unichars -a '\p{Alphabetic}' | wc -l
       14736
    

    And if we include Han and Hangul, which in fact the Alphabetic property does, we just blew the roof off of a hundred thousands code points:

    $ unichars -ua '\p{Alphabetic}' | wc -l
      101539
    

    I hope you can see that you do not want to specifically enumerate these using code point ranges. Down that road lies madness.

    By the way, if you find the unichars script useful, you might also like the uniprops script and perhaps the uninames script.

    Derived Core Properties can be calculated from the other properties.

    The Alphabetic property is defined as: Generated from: Lu + Ll + Lt + Lm + Lo + Nl + Other_Alphabetic

    So, if you take all the characters in Lu, Ll, Lt, Lm, Lo, Nl, and all the characters with the Other_Alphabetic property, you will have the Alphabetic characters.
