## Detailed Description

Handle character conversions to/from server.

## Macro Definition Documentation

## ◆ CHARSIZE

#define CHARSIZE | ( |  | charset | ) |

Value:
( ((charset)->min_bytes_per_char == (charset)->max_bytes_per_char )? \
(charset)->min_bytes_per_char : 0 )

## Function Documentation

## ◆ tds_iconv_alloc()

int tds_iconv_alloc | ( | TDSCONNECTION * | conn | ) |

Allocate iconv stuff.

Returns
  0 for success

## Variable Documentation

## ◆ [struct]

const struct { ... } test_strings[4]

Initial value:
= {
{ 4, "Ao\xD3\xE5" },
{ 6, "Ao\xC3\x93\xC3\xA5" },
