Solutions

1. Rename keys to start with a lowercase letter a-z, e.g. '{name1}' instead of '{Name1}' or '{1name}'.
2. Re-run with throwError=false for tolerant parsing during debugging.
3. Document the accepted grammar: '{' + lowercase-letters + non-zero-leading-digits + '}'.

Example fix

// before
var chunks = StrUtil.GetStrChunk("{Name1}", throwError: true);

// after
var chunks = StrUtil.GetStrChunk("{name1}", throwError: true);

StrUtil.GetStrChunk(template, throwError: false);

try { chunks = StrUtil.GetStrChunk(tpl, throwError: true); }
catch (Exception) { chunks = StrUtil.GetStrChunk(tpl, throwError: false); }

When it happens

Trigger: A placeholder like '{1key}' (starts with a digit), '{Key}' (uppercase), or '{_key}' (underscore) immediately after the '{'.

Common situations: Template/localization strings using uppercase or digits at the start of a placeholder key; placeholders copied from a different template syntax (e.g. {0}, {Name}) into this parser which expects {%key%num} form.
