Indeed this is a serious problem these days, unicode.. which is almost a
virus. In GoLang they use something called "Runes" to try and solve the
problem. Off topic but I wonder if Lazarus/fpc uses something anything
similar to golang's rune's approach or looked into it.
IMO unicode reaches something like Godel's incompleteness problem. You can
never actually prove that a unicode program will work properly nor prove
that it won't have bugs, because unicode creates infinite gotchyas and
unicode is always evolving to have more characters that you didn't know
It makes code inelegant compared to plain english 255 systems like in the
There is an interesting article/video about it on Sucksless, and even this
guy scares me when he talks about unicode even though he is trying to fix
"UTF-8 everywhere? Writing Unicode compliant software that sucks less,
But it of course is not specific to Lazarus. Sorry for slightly off topic.
