I create brand names and to evaluate them properly I must not be influenced by the typeface they are written with. Therefore I'm looking for the most neutral possible font. I don't know if it would be a specific font that is known to be neutral, or if it would be one of the most commonly used that I see everyday.
A simple search for "most neutral font" revealed that there is a font that was designed for the purpose of being more neutral than the common sans serif fonts, by averaging all their characteristics. This font is named Neutral, by Kai Bernau.
So you want to separate a name from its visual appearance. ASCII numbers, Braille and Morse code deliver. I think the idea to discard the visual side is not good because people read business names as whole, they are images. You'll throw away a great part of the available information. Besides with non-visual codes you'll develop some replacement for the visual look, say the rhythm of the word as Morse.
My recommendation: Watch a name with various widely used simple fonts. If one looks acceptable, the name is acceptable.
Not asked: Some attention needs also how the name sounds as spoken.
ADD due the comments:
Get Scanahand or other "handwriting to font converter" and make your own font. The job takes less than half a hour and needs no experience. I guess there's no better way to keep foreign decisions off.
