The Latin alphabet used by Yaron Matras -Romlex- is as well quite accurate phonetically, covering a wide variety of dialectal utterances. However, we prefer to replace the character ‹j› by ‹y›, as the first one may induce to misinterpretation within Roma who are familiar with graphemes of English, French, Spanish and other tongues. Indeed, even though ‹j› is a semivowel equivalent to a short ‹i› in most European languages, it has also a fully consonantal value in the ones mentioned above, being equivalent to ‹ž› in English, ‹ź› in French or Catalan, ‹x› in Castilian Spanish. The grapheme ‹y› does not present this difficulty.

The so-called "standard" alphabet, promoted by the IRU, besides the lack of accuracy and the presence of nonsensical characters that cannot be found in any keyboard, contains also other improper graphemes such as ‹rr›, that is meaningless in Romany, or ‹q›, which has an unnecessary double value besides the fact that such character is used in conventional phonetics to represent the Arabic "qof" and similar sounds, which in Romany is exceptionally present in some dialectal pronunciations of ‹ć› and is not related to the alleged equivalences intended by this alphabet. There are other flaws that we will not consider now, as this alphabet is to be discarded as a practicable Romany script.

Other unsuitable script which has been suggested for Romany language is Devanāgarī, just because this abugida writing system is in modern times related to Sanskrit, which in turn has contributed to the formation of Romany language along with other tongues spoken in the Indus Valley in early times, such as Greek. Like many other theories regarding Roma, this one is based on erroneous patterns and anachronistic historical incongruity. Just to mention a few:
·It is absolutely certain that Roma have never used Devanāgarī, as this writing system did not exist until more than one century after Roma had left the Indus Valley and by the time it appeared Roma were already sojourning in Asia Minor, on their way to Europe.
·Devanāgarī evolved from Brāhmī, which most scholars agree that developed from Imperial Aramaic, the script used by the Persian Empire and widely known in the Indus Valley during the Achaemenian rule. Subsequently, Greek alphabet has been the most used in that region.
·Devanāgarī is connected to Sanskrit only in recent times, since the British colonial rule over India. Indeed, before that time Sanskrit had not any standard alphabet or writing system whatsoever.
Therefore, Imperial Aramaic and Greek alphabets were the most widely used during the development of Romany language, not Devanāgarī.
As we have stated above, there is a general tendency to romanization of non-Latin alphabets, and in some languages with a longstanding literary and cultural tradition expressed in other writing systems, these had been replaced by European alphabets – as for example the Turkic tongues, in which the Arabic-based script has been superseded by Latin or Cyrillic. The idea that Roma might adopt Devanāgarī is unrealistic.
