.tel Russian Language IDN implementation has a feature that mitigates homographic
attacks by blocking a name from being registered if a similar name is already registered.

For every registered Russian language IDN a canonical string will be computed and
stored in the SRS database. The canonical string is produced by mapping every character
in the IDN U-label into the corresponding canonical character as specified in the
character table below. Once a Russian language IDN is registered, other domain names
that map into the same canonical string will be unavailable for registration. Conversely, if
the US ASCII registration exists then the Russian IDN label that maps to the identical
canonical string is unavailable.

The table below lists the characters allowed in the Unicode representation of IDNs
associated with the Russian language. The second column shows the canonical code point
corresponding to the first column. Columns are delimited with semicolons. The ‘#’
symbol denotes start of a comment that continues to the end of line.

Note: as opposed to most other IDN languages supported in .tel, the character table for
the Russian language IDNs does not include US ASCII letters a to z.
