Is it possible to limit characters in TextInputDialog only with letters from English alphabet?

  You can't limit entering characters, but what you can do, is to check the length of the string on complete and then display error message or go back to TextInputDialog, etc

  Yep, like @ar2rsawseen said, we can only check it after.
  
  This is what i do:

  local obtainedText = "This is a text.. 何とか" local _mapnamechar = "[-a-zA-Z0-9()_ !<a href="http://forum.gideros.rocks/profile/%26amp" rel="nofollow">@&amp</a>;*+='?,.<>/]" local checkedText = string.gsub( obtainedText , _mapnamechar, "" ) if string.len( checkedText ) >= 1 then print("Contain something else~") end

  Hi @ar2rsawseen and @tkhnoman. Thank you for answers. I've decided to solve this task with transliteration string entered by user. I hadn't found such solution for Lua and wrote my own transliteration class: https://github.com/romka/lua-transliterator. It's written on pure Lua and can be used outside of Gideros.
  
  To use it with Gideros you should include all files from this repository to Gideros project, and exclude from execution all files from data directory, files from this directory will be included on demand.
