ERROR: LoadError: StringIndexError: invalid index [5205], valid nearby indices [5204]=>'à', [5206]=>' ' Stacktrace: [1] string_index_err(s::String, i::Int64) @ Base ./strings/string.jl:12 [2] getindex @ ./strings/string.jl:469 [inlined] [3] tokenizer(txt::String, config::Main.OteraEngine.ParserConfig) @ Main.OteraEngine ~/Documents/OpenProduct/OteraEngine.jl/src/parser.jl:14 [4] parse_template(txt::String, filters::Dict{String, Symbol}, config::Main.OteraEngine.ParserConfig) @ Main.OteraEngine ~/Documents/OpenProduct/OteraEngine.jl/src/parser.jl:518 [5] Main.OteraEngine.Template(txt::String; path::Bool, filters::Dict{String, Symbol}, config_path::String, config::Dict{String, Union{Bool, String}}) @ Main.OteraEngine ~/Documents/OpenProduct/OteraEngine.jl/src/template.jl:59 [6] Template @ ~/Documents/OpenProduct/OteraEngine.jl/src/template.jl:32 [inlined] [7] (::var"#1#2")(f::IOStream) @ Main ~/Documents/OpenProduct/openproduct-docs/communication/sendMail.jl:39 [8] open(::var"#1#2", ::String, ::Vararg{String}; kwargs::@Kwargs{}) @ Base ./io.jl:396 [9] open(::Function, ::String, ::String) @ Base ./io.jl:393 [10] top-level scope @ ~/Documents/OpenProduct/openproduct-docs/communication/sendMail.jl:37 in expression starting at /home/alberic/Documents/OpenProduct/openproduct-docs/communication/sendMail.jl:37
