| 1 | MUTT HACKERS BEWARE |
|---|
| 2 | |
|---|
| 3 | A word of warning about string comparisons: Since mutt may run in a |
|---|
| 4 | huge variety of locales, case-insensitive string comparisons and |
|---|
| 5 | case conversions may be dangerous. For instance, in iso-8859-9, |
|---|
| 6 | tolower('I') is DIFFERENT from 'i' - it's indeed the Turkish dotless |
|---|
| 7 | lowercase i. |
|---|
| 8 | |
|---|
| 9 | For this reason, always use the ascii_* functions defined in ascii.h |
|---|
| 10 | and implemented in ascii.c when comparing or handling strings which |
|---|
| 11 | are defined as us-ascii. This concerns lots of text-based |
|---|
| 12 | protocols, message header tags, character set names, domain names, |
|---|
| 13 | e-mail addresses, etc. |
