Scans the string for colour codes and strips them. | |
void | strtolower (char *str) |
Convert the given string to lowercase, only works with ASCII! | |
static bool | StrEmpty (const char *s) |
static int | ttd_strnlen (const char *str, int maxlen) |
Get the length of a string, within a limited buffer. | |
char * | md5sumToString (char *buf, const char *last, const uint8 md5sum[16]) |
Convert the md5sum number to a 'hexadecimal' string, return next pos in buffer. | |

Only allow certain keys. | |

size_t | Utf8Encode (char *buf, WChar c) |
size_t | Utf8TrimString (char *s, size_t maxlen) |
Properly terminate an UTF8 string to some maximum length. | |
static WChar | Utf8Consume (const char **s) |
static size_t | Utf8CharLen (WChar c) |
Return the length of a UTF-8 encoded character. | |
static size_t | Utf8EncodedCharLen (char c) |
Return the length of an UTF-8 encoded value based on a single char. | |
static bool | IsUtf8Part (char c) |
static char * | Utf8PrevChar (const char *s) |
Retrieve the previous UNICODE character in an UTF-8 encoded string. | |
static bool | IsPrintable (WChar c) |
static bool | IsWhitespace (WChar c) |

bool IsValidChar | ( | WChar | key, | |
CharSetFilter | afilter | |||
) |
Only allow certain keys.
You can define the filter to be used. This makes sure no invalid keys can get into an editbox, like BELL.
key | character to be checked | |
afilter | the filter to use |

void strtolower | ( | char * | str | ) |
Convert the given string to lowercase, only works with ASCII!
Convert the given string to lowercase, only works with ASCII!
NOTE: only support ASCII characters, no UTF8 fancy. As currently the function is only used to lowercase data-filenames if they are not found, this is sufficient. If more, or general functionality is needed, look to r7271 where it was removed because it was broken when using certain locales: eg in Turkish the uppercase 'I' was converted to '?', so just revert to the old functionality
