This sounds for me like an OTP (Omega Translation Process) input filter. With Omega you can do a lot of manipulation (notably character encoding conversion and various more or less complicated character cluster->glyph transformations e.g. for Hebrew or Arabic) of text before TeX sees the text. You can avoid any active characters.    Werner
