Prior to this commit, only the letters 'A' - 'Z' (ignoring case) were supported in identifiers (i.e., property, field, and variable names). This known (yet undocumented) limitation prevented the use of characters such as 'ü', 'ñ', 'é' as well as letters from other character sets such as Chinese, Japanese, Cyrillic, etc. This commit lifts that restriction by delegating to Character.isLetter() to determine if a character in a SpEL expression is a letter.
