Please read 'code units' instead of “characters”.

The polysemics of the underscore is another collateral issue. In the strings above, 
its current function of a space replacement mixes up with its possible TeX value. 
I wonder whether the LaTeX converter is able to parse that correctly. 

Please note, too, that the leading space and the low lines are intended to facilitate 
the deletion of the message by hitting Ctrl + Backspace.

When that happened, it was set to a higher value. Then Iʼve shortened the output 
string and set “maxout="20"”.

Anyhow, this is no longer an issue here, and this shortcoming is mentioned only for 
equalityʼs sake.
