Dear Igor,

Thank you for your prompt response.

I hope this email gets delivered with the images as it is better that way to convey what we are trying to achieve.

Let’s use Armenian Small Letter HO (U+570) as an example. Below, you should see the three visual representations from 1) compart.com<https://www.compart.com/en/unicode/U+0570> (the URL you recommended), 2) Unicode<https://unicode.org/cldr/utility/character.jsp?a=570&B1=Show> and 3) The Armenian LGR proposal.

  *   The visual representations (i.e. type face) from compart.com and Unicode match, but the representation in the Armenian LGR proposal is different.
  *   The Armenian LGR proposes Latin Small Letter H as variant of Armenian Small Letter HO because they were found to be homoglyphs per the panel.
  *   The Latin GP wishes to learn what are the common type faces used in internet applications, such as browsers in order to do our variant analysis.
  *   Question: is the following premise true? The type face used by compart.com or Unicode (shown above) is not representative of current use by internet applications.
  *   Question: which type face(s) does the Armenian GP used in your LGR document as seen above? And, is the type face used in Armenian LGR proposal representative of current use by internet applications?

I hope this is helpful. Alternatively, I can jump into a quick call to explain all this.

Thank you.

Dear Dennis,
We are very glad to receive a letter from you and the Latin GP. It signifies that we can finalize soon our Proposal for an Armenian Script Root Zone LGR.
The most commonly used Armenian type face (based on current use on Internet applications, such as websites and browsers) can be seen here https://www.compart.com/en/unicode/scripts/Armn . It differs slightly from the Unicode default. However we are ready to discuss your objections and come to an agreement. What code point seems doubtful to you to be considered as a homoglyph?
Thank you and best regards
Igor Mkrtumyan
Armenian GP

Subject: Latin-Armenian cross-script variant analysis

Dear Armenian GP,

The Latin GP is initiating work on Latin/Armenian cross-script variant analysis. To this end, we want to use the Proposal for an Armenian Script Root Zone LGR, version 7 of 2015-11-05 as a reference.

In your proposal, there are seven cross-script Latin/Armenian variant sets. However, we cannot replicate your results for the exception of one code point. The reason for this is the choice of type face. Our wg cannot find the type face the Armenian GP used to do the visual comparison. We kindly ask your help in understanding the following:
·         What is the type face (i.e. font) that the Armenian GP used in their analysis?
·         Was the decision of using a different type face different that the Unicode’s default (i.e. type face used in Unicode code charts) based on current use on Internet applications, such as websites and browsers? Please elaborate to the extent possible.

Thank you in advance for taking the time to answer this email.

Latin GP, variant group
